Deserialization of Untrusted Data vulnerability in bulktheme WOOEXIM wooexim allows Object Injection.This issue affects WOOEXIM: from n/a through <= 5.0.0.
Security readout for executives and security teams
Plain-English summary
CVE-2025-23944 is a high-severity flaw in the WordPress WOOEXIM plugin. An authenticated low-privilege user could abuse unsafe PHP deserialization to inject objects, potentially affecting confidentiality, integrity, and availability. The source bundle does not name active exploitation or a fixed version.
Executive priority
Treat this as a priority remediation item for any WordPress site using WOOEXIM, especially customer-facing or registration-enabled sites. If WOOEXIM is not business-critical, removing or disabling it is the fastest risk reduction while waiting for confirmed vendor guidance.
Technical view
The issue is CWE-502 deserialization of untrusted data in bulktheme WOOEXIM, package slug wooexim, affecting versions through 5.0.0. CVSS 3.1 is 8.8 with network attack vector, low complexity, low privileges required, no user interaction, and high C/I/A impact.
Likely exposure
Exposure is limited to WordPress sites running WOOEXIM through version 5.0.0. Because the CVSS vector requires PR:L, anonymous exploitation is not supported by the provided evidence, but sites with open registration or many low-privilege users have a larger practical attack surface.
Exploitation context
The bundle does not show CISA KEV listing, public exploit confirmation, or active exploitation evidence. Object injection impact can depend on reachable code paths and available PHP gadget chains, so site-specific risk may vary.
Researcher notes
Key uncertainty is remediation status: the provided sources identify affected versions but do not name a fixed release. Validate plugin presence, privilege requirements, and reachable deserialization paths in a controlled environment without developing weaponized payloads.
Mitigation direction
Inventory WordPress sites for the wooexim plugin and installed version.
Disable or remove WOOEXIM where business use is not required.
Check Patchstack, CVE, and vendor guidance for a fixed release or official mitigation.
Restrict creation and use of low-privilege WordPress accounts.
Review least-privilege settings for users who can access plugin-related functionality.
Validation and detection
Confirm whether WOOEXIM is installed and version is <= 5.0.0.
Verify whether public registration or broad low-privilege access is enabled.
Check WordPress and web logs for suspicious authenticated plugin activity.
Review security tooling for alerts tied to CWE-502 or PHP object injection.
Track vendor advisories until a patched version or workaround is confirmed.
