Vulnerabilities

oaskit versions 0.1.0 through before 0.14.1 contain a reflected cross-site scripting flaw in Oaskit.ErrorHandler.Default (format_reason/4 and reason_to_html/1), which renders request-validation failures as an HTML page whenever the request's Accept header includes html and interpolates request-controlled strings without HTML escaping. The unescaped values are object keys from the request body or from object/deepObject query parameters (reflected in the JSON Schema error's instance path, e.g. when a schema uses additionalProperties: false) and the raw Content-Type header (reflected in unsupported-media-type errors); because browsers send Accept: text/html on ordinary navigation, a single crafted GET link such as one carrying a key like filter[ ]=x is sufficient to inject and execute script, with no form POST or attacker-hosted script required. The injected script runs in the origin of the application using oaskit, giving the attacker access to that origin's cookies, session, and same-origin responses as the victim. Any Elixir/Phoenix application using an affected oaskit version is exposed by default, since Oaskit.Plugs.ValidateRequest defaults :html_errors to true and :error_handler to the vulnerable default handler, so no opt-in is needed. No exploitation in the wild is known at this time; the flaw has a CVSS 4.0 score of 5.1 (medium), EPSS of 0.2% over 30 days, is not in CISA KEV, and a public advisory/PoC exists (GHSA-h7xw-x8wr-xpcc).

Do: Upgrade oaskit to 0.14.1 or later. Applications that cannot upgrade immediately should set :html_errors to false (or supply a custom error handler that HTML-escapes reflected values) on Oaskit.Plugs.ValidateRequest, since the vulnerable default handler is enabled by default. Audit whether your application renders validation errors to browser navigations (e.g., GET endpoints with object/deepObject query parameters rejected under additionalProperties: false) and whether links to them could be attacker-crafted.

Kludex Starlette prior to version 1.0.1 did not validate the HTTP Host request header before using it to reconstruct request.url, an inconsistency classified as HTTP request/response smuggling (CWE-444). Because routing operates on the raw ASGI scope path while request.url is rebuilt from the unvalidated Host header, an attacker can send a malformed Host header so that request.url.path differs from the path the router actually processed. Any middleware or endpoint that enforces security restrictions based on request.url rather than the raw scope path can then be tricked into approving requests that should have been blocked, bypassing those controls. All Starlette deployments below 1.0.1 are affected, both direct users and downstream products that bundle the library, including Red Hat offerings such as Ansible Automation Platform, OpenShift AI, OpenShift Lightspeed, Satellite, AI Inference Server, Migration Toolkit for Applications, and Enterprise Linux AI. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-09-02, confirming active exploitation; related reporting describes attackers deploying reverse shells and crypto miners, and EPSS ranks it in the 98th percentile with a 36.3% probability of exploitation within 30 days.

Do: Upgrade Starlette to 1.0.1 or later, which validates the Host header against RFC 9112/RFC 3986 grammar and falls back to scope['server'] for malformed values, and apply the corresponding Red Hat updates for each bundled product listed above. Until patched, review middleware and endpoints that enforce security decisions from request.url and validate or pin the Host header at your reverse proxy or load balancer. As a KEV entry, federal agencies must patch per BOD 26-04 timelines based on each asset's internet exposure, and operators of internet-facing AI infrastructure should verify their Starlette/FastAPI dependency versions.

Bludit is vulnerable to Stored Cross-Site Scripting (XSS) in its page creating functionality. An authenticated attacker with page creation privileges (such as Author, Editor, or Administrator) can embed a malicious JavaScript payload in the tags field of a newly created article. This payload will be executed when a victim visits the URL of the uploaded resource. The uploaded resource itself is accessible without authentication. Critically, this vulnerability could be used to automatically create a new site administrator if the victim has enough privileges. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only versions 3.17.2 and 3.18.0 were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Bludit’s API plugin allows an authenticated attacker with a valid API token to upload files of any type and extension without restriction, which can then be executed, leading to Remote Code Execution. This issue was fixed in 3.18.4.

Bludit version 3.16.1 contains a cross-site request forgery (CSRF) vulnerability in the /admin/uninstall-plugin/ and /admin/install-theme/ endpoints. The application does not implement anti-CSRF tokens or other request origin validation mechanisms for these administrative actions. An attacker can induce an authenticated administrator to visit a malicious page that silently submits crafted requests, resulting in unauthorized plugin uninstallation or theme installation. This may lead to loss of functionality, execution of untrusted code via malicious themes, and compromise of system integrity.

A local information disclosure vulnerability exists in the Ludashi driver before 5.1025 due to a lack of access control in the IOCTL handler. This driver exposes a device interface accessible to a normal user and handles attacker-controlled structures containing the lower 4GB of physical addresses. The handler maps arbitrary physical memory via MmMapIoSpace and copies data back to user mode without verifying the caller's privileges or the target address range. This allows unprivileged users to read arbitrary physical memory, potentially exposing kernel data structures, kernel pointers, security tokens, and other sensitive information. This vulnerability can be further exploited to bypass the Kernel Address Space Layout Rules (KASLR) and achieve local privilege escalation.

Bludit versions before 3.13.1 contain an authenticated file download vulnerability in the Backup Plugin that allows logged-in users to access arbitrary files. Attackers can exploit the plugin's download functionality by manipulating file path parameters to read sensitive system files through directory traversal.

A security vulnerability has been identified in Bludit, allowing authenticated attackers to execute arbitrary code through the Image API. This vulnerability arises from improper handling of file uploads, enabling malicious actors to upload and execute PHP files.

An issue was found in bludit v3.13.0, unsafe implementation of the backup plugin allows attackers to upload arbitrary files.

A vulnerability was found in Bludit 3.13.1. It has been declared as problematic. This vulnerability affects the endpoint /admin/new-content of the New Content module. The manipulation of the argument content with the input leads to cross site scripting. The attack can be initiated remotely but requires an authentication. The exploit has been disclosed to the public and may be used.

Asciidoctor-include-ext is Asciidoctor’s standard include processor reimplemented as an extension. Versions prior to 0.4.0, when used to render user-supplied input in AsciiDoc markup, may allow an attacker to execute arbitrary system commands on the host operating system. This attack is possible even when `allow-uri-read` is disabled! The problem has been patched in the referenced commits.
