CVE-2025-63016: 
WordPress vulnerability analysis and mitigation

CVE-2025-63016 is a Missing Authorization (Broken Access Control) vulnerability in the QuadLayers TikTok Feed WordPress plugin (wp-tiktok-feed). It allows unauthenticated network attackers to perform unauthorized actions due to incorrectly configured access control security levels. The vulnerability was discovered by researcher Legion Hunter, reported on October 27, 2025, and published by Patchstack on December 31, 2025. It affects all versions of the plugin through 4.6.6 (the affected version range has been updated over time from ≤4.6.4 to ≤4.6.6). The CVSS v3.1 base score is 5.3 (Medium), assigned by Patchstack (Patchstack, Red Hat CVE).

The vulnerability is classified as CWE-862 (Missing Authorization), meaning one or more plugin functions fail to perform adequate authorization checks before executing privileged or sensitive operations. This allows unauthenticated remote attackers to invoke these functions over the network without any credentials or user interaction, exploiting incorrectly configured access control levels. The attack vector is network-based, requires low complexity, and no privileges or user interaction are needed. No public proof-of-concept exploit code has been referenced, but the class of vulnerability is commonly targeted in mass-exploit campaigns against WordPress plugins (Patchstack).

Successful exploitation results in a low integrity impact — unauthenticated attackers can modify application data or trigger restricted plugin functionality without authorization. There is no confidentiality or availability impact according to the CVSS assessment. While the individual impact is limited, Patchstack notes that vulnerabilities of this class are frequently used in mass-exploit campaigns targeting thousands of WordPress sites simultaneously, regardless of site size or traffic (Patchstack).

No public exploit code or active in-the-wild exploitation has been confirmed for CVE-2025-63016. The EPSS score is approximately 0.028% (0.000280), indicating a very low probability of exploitation in the near term (Feedly). The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies the priority as "Low" and notes the issue is unlikely to be exploited, though the broken access control class is broadly targeted in automated WordPress scanning campaigns (Patchstack).

As of the latest available information, no official patch has been released by the plugin developer for the QuadLayers TikTok Feed plugin (wp-tiktok-feed); all versions through 4.6.6 remain listed as vulnerable (Patchstack). Recommended actions include:

• Disable or remove the QuadLayers TikTok Feed plugin until a patched version is available.
• Monitor the WordPress plugin repository and Patchstack for an updated, patched release.
• Use a WAF or virtual patching solution (such as Patchstack) to block exploitation attempts while awaiting an official fix.
• Contact your hosting provider or web developer if you are unable to manage the plugin directly.

The vulnerability was discovered by independent researcher Legion Hunter and responsibly disclosed through Patchstack's vulnerability disclosure program. Patchstack published the advisory on December 31, 2025, and the CVE record has been updated multiple times to reflect an expanding affected version range (from ≤4.6.4 to ≤4.6.6). No significant broader media coverage or notable researcher commentary beyond the Patchstack advisory has been identified (Patchstack).
