Vulnerabilities

SimpleSAMLphp versions before 1.18.6 contain an information disclosure vulnerability. Prior to 2.4.7 and 2.5.2, SimpleSAMLphp's SAML SP ACS path does not enforce the IdP selected for an SP-initiated login when unsigned Response/InResponseTo is combined with a signed assertion lacking SubjectConfirmationData/InResponseTo, allowing a response issued by one trusted IdP to be bound to SP state created for another IdP and bypass flows that route users to a specific IdP, including deployments that set enable_unsolicited to false. This issue is fixed in versions 2.4.7 and 2.5.2.

CVE-2026-48558 is an authentication bypass (CWE-347, improper verification of cryptographic signature) in the SimpleHelp remote access/support platform's OpenID Connect (OIDC) login flow, where submitted identity tokens are accepted without verifying their signature. It is triggered when OIDC authentication is configured: a remote, unauthenticated attacker can submit a forged token containing arbitrary identity claims and obtain a fully authenticated technician session, and in some configurations this also bypasses multi-factor authentication. Related reporting describes a path from this bypass to remote code execution. Only SimpleHelp deployments using OIDC-based (e.g., SSO) authentication are affected; deployments relying on local SimpleHelp accounts are not described as affected. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-29, confirming exploitation in the wild, with a 30% EPSS probability of exploitation within 30 days and no public proof-of-concept known.

Do: Update SimpleHelp to the latest release per vendor instructions, prioritizing any internet-facing server (CISA KEV listing means federal agencies must act under BOD 26-04). Until patched, restrict access to the SimpleHelp web login to trusted management networks (VPN/firewall) or temporarily switch from OIDC to local-account authentication with MFA. Verify whether OIDC is enabled on each instance and review technician login logs for sessions created with unusual or unexpected identity claims.

Simple Hierarchical Select (SHS) for Drupal 7 contains cross-site scripting risk due to improper output escaping of term-derived text. Confirmed affected paths include field formatter output (shs_field_formatter_view) and term-tree child-term data generation (shs_term_get_children). Malicious taxonomy term names can be rendered unsafely depending on output context. This affects versions from 7.x-1.0 through (and including) 7.x-1.10.

SimpleSAMLphp-casserver is a CAS 1.0 and 2.0 compliant CAS server in the form of a SimpleSAMLphp module. In versions below 6.3.1 and 7.0.0, the logout endpoint accepts a url query parameter to redirect to. casserver treats that url as trusted, and either (depending on configuration) redirects the browser there, or shows a "you've been logged out" page with a link to continue to that url. Impacted configs include 'enable_logout' => true, and 'skip_logout_page' -> true. This issue has been resolved in versions 6.3.1 and 7.0.0.

Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for [CVE-2022-25912](https://security.snyk.io/vuln/SNYK-JS-SIMPLEGIT-3112221) that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source.

simple-git enables running native Git commands from JavaScript. Versions up to and including 3.31.1 allow execution of arbitrary commands through Git option manipulation, bypassing safety checks meant to block dangerous options like -u and --upload-pack. The flaw stems from an incomplete fix for CVE-2022-25860, as Git's flexible option parsing allows numerous character combinations (e.g., -vu, -4u, -nu) to circumvent the regular-expression-based blocklist in the unsafe operations plugin. Due to the virtually infinite number of valid option variants that Git accepts, a complete blocklist-based mitigation may be infeasible without fully emulating Git's option parsing behavior. This issue has been fixed in version 3.32.0.

SimplePress CMS 1.0.7 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the 'p' and 's' parameters. Attackers can send GET requests with crafted SQL payloads to extract sensitive database information including usernames, database names, and version details.

xml-security is a library that implements XML signatures and encryption. Prior to versions 2.3.1 and 1.13.9, XML nodes encrypted with either aes-128-gcm, aes-192-gcm, or aes-256-gcm lack validation of the authentication tag length. An attacker can use this to brute-force an authentication tag, recover the GHASH key, and decrypt the encrypted nodes. It also allows to forge arbitrary ciphertexts without knowing the encryption key. This vulnerability is fixed in 2.3.1 and 1.13.9.

GetSimple CMS is a content management system. The massiveAdmin plugin (v6.0.3) bundled with GetSimpleCMS-CE v3.3.22 allows an authenticated administrator to overwrite the gsconfig.php configuration file with arbitrary PHP code via the gsconfig editor module. The form lacks CSRF protection, enabling a remote unauthenticated attacker to exploit this via Cross-Site Request Forgery against a logged-in admin, achieving Remote Code Execution (RCE) on the web server.

`simple-git`, an interface for running git commands in any node.js application, has an issue in versions 3.15.0 through 3.32.2 that allows an attacker to bypass two prior CVE fixes (CVE-2022-25860 and CVE-2022-25912) and achieve full remote code execution on the host machine. Version 3.23.0 contains an updated fix for the vulnerability.

Simple Job Script contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the job_id parameter. Attackers can send POST requests to get_job_applications_ajax.php with malicious job_id values to bypass authentication, extract sensitive data, or modify database contents.

GetSimpleCMS Community Edition (CE) versions prior to 3.3.22 (3.3.16 tested) contains a stored cross-site scripting (XSS) vulnerability in the Theme to Components functionality within components.php. User-supplied input provided to the "slug" field of a component is stored without proper output encoding. While other fields are sanitized using safe_slash_html(), the slug parameter is written to XML and later rendered in the administrative interface without sanitation, resulting in persistent execution of arbitrary JavaScript. An authenticated administrator can inject malicious script content that executes whenever the affected Components page is viewed by any authenticated user, enabling session hijacking, unauthorized administrative actions, and persistent compromise of the CMS administrative interface.

GetSimple CMS is a content management system. All versions of GetSimple CMS have a flaw in the Uploaded Files feature that allows for arbitrary file reads. This issue has not been fixed at the time of publication.

Simple CMS 2.1 contains a remote SQL injection vulnerability that allows privileged attackers to inject unfiltered SQL commands in the users module. Attackers can exploit unvalidated input parameters in the admin.php file to compromise the database management system and web application.

GetSimple CMS My SMTP Contact Plugin 1.1.2 contains a PHP code injection vulnerability. An authenticated administrator can inject arbitrary PHP code through plugin configuration parameters, leading to remote code execution on the server.

CMSimple_XH 1.7.4 contains an authenticated remote code execution vulnerability in the content editing functionality that allows administrative users to upload malicious PHP files. Attackers with valid credentials can exploit the CSRF token mechanism to create a PHP shell file that enables arbitrary command execution on the server.

CMSimple 5.4 contains an authenticated remote code execution vulnerability that allows logged-in attackers to inject malicious PHP code into template files. Attackers can exploit the template editing functionality by crafting a reverse shell payload and saving it through the template editing endpoint with a valid CSRF token.

A stored cross-site scripting (XSS) vulnerability in Simple Machines Forum v2.1.6 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Forum Name parameter.

CMSimple 5.15 contains a remote command execution vulnerability that allows authenticated attackers to modify file extensions and upload malicious PHP files. Attackers can append ',php' to Extensions_userfiles and upload a shell script to the media directory to execute arbitrary code on the server.

Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting") vulnerability in Drupal Simple multi step form allows Cross-Site Scripting (XSS).This issue affects Simple multi step form: from 0.0.0 before 2.0.0.

An authenticated arbitrary file upload vulnerability in the /uploads/ endpoint of CMS Made Simple Foundation File Manager v2.2.22 allows attackers with Administrator privileges to execute arbitrary code via uploading a crafted PHP file.

An unauthenticated reflected cross-site scripting vulnerability in the query handling of CMSimpleXH allows remote attackers to inject and execute arbitrary JavaScript in a victim's browser via a crafted request (e.g., a maliciously crafted POST login). Successful exploitation may lead to theft of session cookies, credential disclosure, or other client-side impacts.

Authentication Bypass Using an Alternate Path or Channel vulnerability in Drupal Simple OAuth (OAuth2) & OpenID Connect allows Authentication Bypass.This issue affects Simple OAuth (OAuth2) & OpenID Connect: from 6.0.0 before 6.0.7.

Inclusion of Functionality from Untrusted Control Sphere vulnerability in Simplehelp.This issue affects Simplehelp: before 5.5.12.

Simple File List, a WordPress plugin for publishing downloadable file lists, is vulnerable to unauthenticated remote code execution in all versions up to and including 4.2.2 (CWE-434). The flaw is in the plugin's rename function: an attacker first uploads a file containing PHP code with a harmless .png extension, then abuses the rename function to change that file's extension to .php, turning the upload into an executable script on the server. Because the upload and rename operations require no authentication, any remote attacker can run arbitrary code on the web server, which can lead to complete site compromise, webshells, or backdoor installation. All WordPress sites running Simple File List 4.2.2 or earlier are affected, on the order of tens of thousands of installations based on the plugin's active-install count. Public proof-of-concept exploits are available and the vulnerability carries a high EPSS score (44.7% probability of exploitation in 30 days, 99th percentile), though it is not yet listed in CISA's Known Exploited Vulnerabilities catalog.

Do: Update Simple File List to the latest release (any version newer than 4.2.2); there is no configuration mitigation since the attack requires no authentication. Until patched, check the plugin's upload directory for unexpected .php files and renamed .png uploads, and review web server logs for unauthenticated requests to the plugin's upload/rename endpoints. Given ongoing WordPress plugin exploitation campaigns reported in 2026 (e.g., WP-SHELLSTORM), also scan already-patched sites for webshells and backdoors in case exploitation already occurred.

GetSimple CMS is a content management system. In versions starting from 3.3.16 to 3.3.21, an authenticated user with access to the Edit component can inject arbitrary PHP into a component file and execute it via a crafted query string, resulting in Remote Code Execution (RCE). This issue is set to be patched in version 3.3.22.

A vulnerability, which was classified as problematic, has been found in CMS Made Simple 2.2.21. This issue affects some unknown processing of the component Design Manager Module. The manipulation of the argument Description leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Vulnerability in Drupal Simple GTM.This issue affects Simple GTM: *.*.

The Simple Banner WordPress plugin before 3.0.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

A vulnerability was found in SimpleMachines SMF 2.1.4. It has been classified as problematic. This affects an unknown part of the file ManageNews.php. The manipulation of the argument subject/message leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The vendor does not declare this issue a security vulnerability due to authentication requirements before being able to access any feature in the software that allows file modification.

The Simple:Press Forum plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.10.12. This is due to missing or incorrect nonce validation on the 'sp_save_edited_post' function. This makes it possible for unauthenticated attackers to modify a forum post via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Simple:Press Forum WordPress plugin before 6.10.11 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting.
