CVE-2026-22507: 
WordPress vulnerability analysis and mitigation

CVE-2026-22507 is a Deserialization of Untrusted Data vulnerability (PHP Object Injection) in the AncoraThemes Beelove WordPress theme. It affects all versions of the Beelove theme up to and including 1.2.6. The vulnerability was published on March 25, 2026, and was assigned by Patchstack. It carries a CVSS v3.1 base score of 9.8 (Critical), reflecting its network-accessible, unauthenticated, and no-user-interaction attack profile (Feedly, Patchstack).

The root cause is improper deserialization of untrusted user-supplied data within the Beelove WordPress theme (CWE-502: Deserialization of Untrusted Data). An attacker can craft a malicious serialized PHP object and submit it via a network request to a vulnerable endpoint exposed by the theme, triggering object injection (CAPEC-586). Because no authentication or user interaction is required and attack complexity is low, exploitation is straightforward for any remote attacker. No specific technical write-up or public PoC code has been identified at this time (Feedly, Patchstack).

Successful exploitation allows an attacker to inject malicious PHP objects, potentially manipulating application logic and achieving remote code execution on the underlying WordPress server. The vulnerability has high impact across confidentiality, integrity, and availability — an attacker could exfiltrate sensitive data, modify site content or database records, install backdoors, or render the site unavailable. Given the unauthenticated network-accessible nature of the flaw, any WordPress site running the affected Beelove theme version is at risk without any prerequisite access (Feedly).

No public proof-of-concept exploit code has been observed, and there is no evidence of active in-the-wild exploitation at this time. The EPSS score is approximately 0.024%, indicating a currently low probability of exploitation in the near term. The vulnerability has not been listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No specific threat actor attribution has been reported (Feedly).

The primary remediation is to update the AncoraThemes Beelove WordPress theme to a version newer than 1.2.6, which contains the patch for this vulnerability. Site administrators should audit all WordPress installations for the presence of Beelove theme versions 1.2.6 or earlier and prioritize upgrading immediately given the critical CVSS score. As a general defense-in-depth measure, consider using a web application firewall (WAF) to filter malicious serialized payloads while patching is underway (Feedly, Patchstack).

The vulnerability was noted in the Wordfence Intelligence Weekly WordPress Vulnerability Report for the week of March 9–15, 2026, and was tracked by VulDB shortly after disclosure. No significant broader media coverage or notable researcher commentary beyond standard vulnerability reporting has been identified (Wordfence Blog).
