Security readout for executives and security teams
Plain-English summary
CVE-2022-2437 affects the WordPress Feed Them Social plugin through version 2.9.8.5. An unauthenticated attacker may trigger unsafe PHP object deserialization through the fts_url parameter if they can also place a malicious serialized file where the site can read it. Successful exploitation could affect confidentiality, integrity, and availability.
Executive priority
Treat as urgent for affected public WordPress sites because the issue is unauthenticated, critical severity, and can lead to full site compromise when prerequisites are met. Prioritize inventory, update, and exposure reduction before routine backlog work.
Technical view
The issue is CWE-502 deserialization of untrusted input. The fts_url parameter can call files through a PHAR wrapper, causing PHP metadata deserialization. The published CVSS 3.1 score is 9.8. Impact depends on a usable POP chain and successful attacker upload or placement of a serialized payload file.
Likely exposure
Internet-facing WordPress sites using Feed Them Social versions up to and including 2.9.8.5 are the relevant exposure. Risk is higher where unauthenticated users can upload files, abused upload paths exist, or another weakness lets attackers place readable files on the server.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. The vulnerability is network-reachable and unauthenticated, but practical exploitation requires a serialized payload file and a suitable PHP object chain in the environment.
Researcher notes
Focus validation on the exact plugin version, reachable fts_url handling, upload or file-placement paths, and available POP chains. Do not assume exploitability without confirming the payload placement prerequisite and environment-specific object chain conditions.
Mitigation direction
- Upgrade Feed Them Social to a version newer than 2.9.8.5 following vendor guidance.
- Remove or disable the plugin where it is not business-critical.
- Restrict unauthenticated file upload capabilities across the WordPress site.
- Review vendor and Wordfence advisories for current remediation guidance.
- Use a WAF or WordPress security control to reduce suspicious fts_url requests.
Validation and detection
- Inventory WordPress sites for the Feed Them Social plugin and installed version.
- Confirm every installation is removed, disabled, or above version 2.9.8.5.
- Review web logs for suspicious fts_url requests and PHAR wrapper references.
- Audit upload locations for unexpected files readable by the web server.
- Check whether other plugins or themes provide relevant PHP object chains.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
