AI Analysis
Technical Summary
The 'Posts per Cat' WordPress plugin by urkekg suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'ppc' shortcode. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript code that executes in the context of any user viewing the injected page. This vulnerability affects all versions up to 1.4.2. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required at low level, no user interaction, scope changed, with low confidentiality and integrity impact and no availability impact.
Potential Impact
An attacker with contributor-level access or higher can exploit this vulnerability to inject malicious scripts that execute in the browsers of users visiting the compromised pages. This can lead to theft of user credentials, session hijacking, or other actions performed with the victim's privileges. The confidentiality and integrity of user data may be partially compromised, but availability is not affected. Since the plugin is unmaintained, no official fix is available, increasing the risk for sites still using it.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability as the 'Posts per Cat' plugin is unmaintained. Site administrators should consider disabling or removing the plugin to eliminate the risk. Alternatively, restricting contributor-level access or higher users from untrusted parties can reduce the likelihood of exploitation. Monitor for any updates or community patches, but currently, no vendor-provided remediation exists.
