CVE-2024-7426
📋 TL;DR
The PeepSo WordPress plugin discloses full server path information to unauthenticated attackers through error messages in the sse.php file. This vulnerability affects all WordPress sites using PeepSo plugin versions up to 6.4.6.0. While the path disclosure alone doesn't enable direct compromise, it provides reconnaissance data that can assist in exploiting other vulnerabilities.
💻 Affected Systems
- PeepSo - Social Network, Membership, Registration, User Profiles WordPress plugin

Peepso by Peepso
⚠️ Risk & Real-World Impact
Worst Case
Attackers combine path disclosure with another vulnerability (like file inclusion or directory traversal) to achieve remote code execution or sensitive data exposure.
Likely Case
Attackers gather reconnaissance information about server structure to plan targeted attacks, potentially accelerating exploitation of other vulnerabilities.
If Mitigated
Path information is exposed but cannot be leveraged due to proper security controls and absence of other vulnerabilities.
🎯 Exploit Status
Exploitation requires direct access to sse.php file and triggering error conditions. No authentication required.
🛠️ Fix & Mitigation
