Vulnerabilities

Authentication Bypass Using an Alternate Path or Channel vulnerability in Drupal CAPTCHA Protected Page allows Functionality Bypass. This issue affects CAPTCHA Protected Page versions: from 0.0.0 to 1.0.2.

PTC Windchill and FlexPLM contain an improper input validation flaw (CWE-20) with an associated deserialization of untrusted data weakness (CWE-502) that allows an unauthenticated, remote attacker to execute arbitrary code by sending a malicious request over the network. An attacker who can reach a vulnerable Windchill or FlexPLM server can run arbitrary code on it, potentially gaining a foothold for lateral movement; CISA notes the flaw is being used in ransomware campaigns. All organizations running PTC Windchill or FlexPLM are affected, and the available data does not specify affected version ranges. The vulnerability was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-25 with known ransomware use, and EPSS assigns a 40.6% probability of exploitation within 30 days (99th percentile). No CVSS score or public proof-of-concept is available yet, but the KEV listing confirms exploitation in the wild.

Do: Apply the fixes in PTC's security advisory for CVE-2026-12569 to both Windchill and FlexPLM as soon as possible, prioritizing internet-facing instances, and comply with the CISA KEV required action under BOD 26-04 (patch within the required window or discontinue use if mitigations are unavailable). Until patched, restrict network exposure of Windchill/FlexPLM servers and hunt for signs of exploitation or ransomware precursor activity; the available data does not list specific patched versions, so defer to PTC's advisory.

An issue was discovered in openmptcprouter thru 0.64 in file common/package/utils/sys-upgrade-helper/src/tools/sysupgrade.c in function create_xor_ipad_opad allowing attackers to potentially write arbitrary files or execute arbitrary commands.

Scriptcase 9.10.023 and before is vulnerable to Remote Code Execution (RCE) via the nm_unzip function.

Vulnerability in the Scriptcase application version 9.4.019, which involves the arbitrary upload of a file via /scriptcase/devel/lib/third/jquery_plugin/jQuery-File-Upload/server/php/ via a POST request. An attacker could upload malicious files to the server due to the application not properly verifying user input.

An Insecure Direct Object Reference (IDOR) in PTC ThingWorx v9.5.0 allows attackers to view sensitive information, including PII, regardless of access level.

An uncontrolled search path element vulnerability (DLL hijacking) has been discovered that could allow a locally authenticated adversary to escalate privileges to SYSTEM.

KEPServerEX is vulnerable to a buffer overflow which may allow an attacker to crash the product being accessed or leak information.

An issue was discovered in the hcaptcha (aka hCaptcha for EXT:form) extension before 2.1.2 for TYPO3. It fails to check that the required captcha field is submitted in the form data. allowing a remote user to bypass the CAPTCHA check.

Unauth. Reflected Cross-Site Scripting (XSS) vulnerability in wppal Easy Captcha plugin <= 1.0 versions.

A user could use the “Upload Resource” functionality to upload files to any location on the disk.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kepware KEPServerEX 6.11.718.0. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of text encoding conversions. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-18411.

db_convert.php in ScriptCase through 9.9.008 is vulnerable to Arbitrary File Deletion by an admin via a directory traversal sequence in the file parameter.

The affected products are vulnerable to an improper validation of array index, which could allow an attacker to crash the server and remotely execute arbitrary code.

The Flexible Captcha WordPress plugin through 4.1 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

The reCAPTCHA WordPress plugin through 1.6 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).

The Login No Captcha reCAPTCHA WordPress plugin before 1.7 doesn't check the proper IP address allowing attackers to spoof IP addresses on the allow list and bypass the need for captcha on the login screen.

Cross-Site Request Forgery (CSRF) vulnerability in Vinoj Cardoza's Captcha Code plugin <= 2.7 at WordPress.

The scu-captcha package in PyPI v0.0.1 to v0.0.4 included a code execution backdoor inserted by a third party.

The Contact Form 7 Captcha WordPress plugin before 0.1.2 does not escape the $_SERVER['REQUEST_URI'] parameter before outputting it back in an attribute, which could lead to Reflected Cross-Site Scripting in old web browsers

flask-session-captcha is a package which allows users to extend Flask by adding an image based captcha stored in a server side session. In versions prior to 1.2.1, he `captcha.validate()` function would return `None` if passed no value (e.g. by submitting an having an empty form). If implementing users were checking the return value to be **False**, the captcha verification check could be bypassed. Version 1.2.1 fixes the issue. Users can workaround the issue by not explicitly checking that the value is False. Checking the return value less explicitly should still work.

Axeda agent (All versions) and Axeda Desktop Server for Windows (All versions) may allow an attacker to send certain commands to a specific port without authentication. Successful exploitation of this vulnerability could allow a remote unauthenticated attacker to obtain full file-system access and remote code execution.

The Contact Form With Captcha WordPress plugin is vulnerable to Cross-Site Request Forgery due to missing nonce validation in the ~/cfwc-form.php file during contact form submission, which made it possible for attackers to inject arbitrary web scripts in versions up to, and including 1.6.2.

An issue in the administrator authentication panel of PTCL HG150-Ub v3.0 allows attackers to bypass authentication via modification of the cookie value and Response Path.

The Contact Form 7 Captcha WordPress plugin before 0.0.9 does not have any CSRF check in place when saving its settings, allowing attacker to make a logged in user with the manage_options change them. Furthermore, the settings are not escaped when output in attributes, leading to a Stored Cross-Site Scripting issue.

An XSS issue was discovered in ReCaptcha Solver 5.7. A response from Anti-Captcha.com, RuCaptcha.com, 2captcha.com, DEATHbyCAPTCHA.com, ImageTyperz.com, or BestCaptchaSolver.com in setCaptchaCode() is inserted into the DOM as HTML, resulting in full control over the user's browser by these servers.
