Deeper analysis
CVE-2024-13833 is a PHP Object Injection vulnerability (CWE-502) with a CVSS score of 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) affecting the Album Gallery – WordPress Gallery plugin for WordPress in all versions up to and including 1.6.3. The flaw stems from deserialization of untrusted input sourced from gallery meta, enabling the injection of a PHP Object.
Authenticated attackers possessing Editor-level access or higher can exploit this vulnerability. While no known Property-Oriented Programming (POP) chain exists within the vulnerable plugin itself—limiting standalone impact—the presence of a POP chain from another installed plugin or theme could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute arbitrary code, depending on the chain's capabilities.
Advisories and patches are referenced in the plugin's development changelog at https://plugins.trac.wordpress.org/changeset/3246291/new-album-gallery and Wordfence's threat intelligence at https://www.wordfence.com/threat-intel/vulnerabilities/id/cc7075a6-5609-42ab-a4cb-9d33686c7de0?source=cve, which detail remediation steps including updating the plugin beyond version 1.6.3.

access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
