CVE-2024-5726: CWE-502 Deserialization of Untrusted Data in wpdiscover Timeline Event History
The Timeline Event History plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1 via deserialization of untrusted input 'timelines-data' parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
AI Analysis
Technical Summary
CVE-2024-5726 is a high-severity vulnerability (CVSS 8.8) affecting the Timeline Event History plugin for WordPress (versions up to 3.1). It involves unsafe deserialization of untrusted input ('timelines-data' parameter), enabling PHP Object Injection by authenticated users with Contributor or higher privileges. The vulnerability does not include a known POP chain within the plugin, but if other installed components provide one, attackers could leverage this to perform destructive or unauthorized actions such as deleting files, accessing sensitive data, or executing arbitrary code.
Potential Impact
Successful exploitation requires authenticated access at Contributor level or above. Without a known POP chain in the plugin itself, direct exploitation is limited; however, in environments where additional plugins or themes provide POP chains, attackers could achieve high-impact outcomes including confidentiality, integrity, and availability breaches. This could result in arbitrary file deletion, sensitive data exposure, or remote code execution.
Mitigation Recommendations
No official patch or fix is currently confirmed for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the Timeline Event History plugin if not essential. Monitor for updates from the vendor or WordPress plugin repository regarding a security update.
