CVE-2026-1360 — BuddyPress <= 14.5.0 - Authenticated (Subscriber+) PHP Object Injection via XProfile Field Data
The BuddyPress plugin for WordPress is vulnerable to Deserialization of Untrusted Data in all versions up to, and including, 14.5.0 This is due to the `bp_unserialize_profile_field()` function using `@unserialize()` without the `allowed_classes` parameter on user-controlled XProfile field data. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary PHP objects via XProfile textbox fields, which could lead to remote code execution if a suitable POP chain is available in the WordPress environment.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (BuddyPress BuddyPress).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (insecure deserialization), errors and authentication anomalies.

Weakness class according to MITRE’s CWE catalog.
Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Monitor serialized objects in requests and unexpected processes spawned by the runtime.
