Privilege escalation in CouchCMS allows authenticated Admin-level users to create SuperAdmin accounts by manipulating the f_k_levels_list parameter during user creation requests. Attackers modify the parameter value from 4 to 10 in HTTP POST bodies to bypass authorization controls and gain unrestricted application access. This authenticated attack (PR:H) enables lateral privilege movement from Admin to SuperAdmin, circumventing intended role hierarchy enforcement. Publicly available exploit code exists, lowering exploitation barrier for actors with existing Admin credentials.
CouchCMS 2.2.1 contains a cross-site scripting vulnerability that allows authenticated attackers to execute arbitrary JavaScript by uploading malicious SVG files through the file upload. Rated medium severity (CVSS 5.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
CouchCMS 2.2.1 contains a server-side request forgery vulnerability that allows authenticated attackers to make arbitrary HTTP requests by uploading malicious SVG files. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
** Disputed ** An Information Disclosure vulnerability in CouchCMS 2.4 allow an Admin user to read arbitrary files via traversing directories back after back. It can Disclosure the source code or any other confidential information if weaponize accordingly. [CVSS 6.5 MEDIUM]
CouchCMS versions up to 2.4 use hard-coded cryptographic keys in the reCAPTCHA handler configuration, allowing remote attackers with high complexity to conduct information disclosure attacks against the reCAPTCHA mechanism. The vulnerability stems from improper handling of K_RECAPTCHA_SITE_KEY and K_RECAPTCHA_SECRET_KEY parameters in couch/config.example.php, and publicly available exploit code exists, though real-world exploitation probability remains low (EPSS 0.06%).
An open redirect vulnerability in the sanitize_url() parameter of CouchCMS v2.3 allows attackers to redirect a victim user to an arbitrary web site via a crafted URL. Rated medium severity (CVSS 6.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Couch through 2.0 allows remote attackers to discover the full path via a direct request to includes/mysql2i/mysql2i.func.php or addons/phpmailer/phpmailer.php. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
