CVE-2026-112067—31.6%
——9The extension hides the correct answer to each CAPTCHA inside the image data of the CAPTCHA itself. Anyone who can request a CAPTCHA image can read the answer from it and submit it, so automated clients can pass the challenge. This applies to the default configuration, because the audio feature that causes the answer to be embedded is enabled by default. Forms that rely on the CAPTCHA as their only protection against automated submissions are exposed to abuse by bots.18dCVE-2026-1112785.3 MED25.2%
——8NivoCart through 2.5.1 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to defeat form protection because the expected code is printed as plain text in the HTML. Attackers can fetch protected forms, extract the captcha_image value with a pattern match, and submit it to automate spam, registrations, reviews, and account deletion requests.22dCVE-2024-235674.3 MED23.5%
——7HCL Aftermarket EPC is affected by Sensitive Information in GET method & in URL which allows application to pass sensitive data via URL parameters during normal usage. Data passed in this manner can be exposed because it may end up stored in unintended locations, including server logs, local browser history and proxy logs.36dCVE-2026-130825.3 MED23.5%
——7GD::SecurityImage versions through 1.75 for Perl use rand to generate secrets.
The random method creates the challenge text used for the CAPTCHA by sampling characters from an array using Perl's built-in rand function, and generates a (by default) six-character string.
The built-in rand function is unsuitable for security applications because it is predictable and reversible.14dCVE-2026-499536.5 MED29.8%
——9Discuz! X5.0 releases 20260320 through 20260610 contains a CAPTCHA bypass vulnerability that allows unauthenticated remote attackers to defeat challenge controls by exploiting limited complexity and predictable character sets in generated CAPTCHA images. Attackers can train a custom optical character recognition model against collected CAPTCHA samples to reliably predict challenge text, bypassing protections on login, registration, and other functionality from automated abuse.12dCVE-2026-409355.3 MED12.3%
——4WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/getCaptcha.php` accepts the CAPTCHA length (`ql`) directly from the query string with no clamping or sanitization, letting any unauthenticated client force the server to generate a 1-character CAPTCHA word. Combined with a case-insensitive `strcasecmp` comparison over a ~33-character alphabet and the fact that failed validations do NOT consume the stored session token, an attacker can trivially brute-force the CAPTCHA on any endpoint that relies on `Captcha::validation()` (user registration, password recovery, contact form, etc.) in at most ~33 requests per session. Commit bf1c76989e6a9054be4f0eb009d68f0f2464b453 contains a fix.12d
