Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly remediates the CSRF flaw in wpDiscuz by requiring timely patching to version 7.6.47 or later, which implements proper CSRF protections.

SC-23 Session Authenticity good match

prevent

Enforces session authenticity mechanisms such as anti-CSRF tokens to prevent forged GET requests from triggering comment deletions.

SI-10 Information Input Validation partial match

prevent

Validates information inputs at web endpoints to reject unauthorized or improperly formatted HMAC-keyed GET requests for destructive actions.

NVD Description

wpDiscuz before 7.6.47 contains a cross-site request forgery vulnerability that allows attackers to delete all comments associated with an email address by crafting a malicious GET request with a valid HMAC key. Attackers can embed the deletecomments action URL in…

image tags or other resources to trigger permanent deletion of comments without user confirmation or POST-based CSRF protection.

Deeper analysisAI

CVE-2026-22202 is a cross-site request forgery (CSRF) vulnerability, classified under CWE-352, affecting the wpDiscuz WordPress plugin in versions prior to 7.6.47. The flaw enables attackers to delete all comments associated with a specific email address by crafting a malicious GET request that includes a valid HMAC key. This request lacks user confirmation or POST-based CSRF protection, making it exploitable through embedded resources such as image tags.

Attackers with network access can exploit this vulnerability without privileges (PR:N), though it requires user interaction (UI:R), such as a victim visiting a malicious webpage. By embedding the deletecomments action URL in images or other resources, attackers can trigger permanent deletion of all comments linked to the victim's email address upon page load. The vulnerability yields high integrity (I:H) and availability (A:H) impacts with no confidentiality effects, earning a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H).

Mitigation involves updating wpDiscuz to version 7.6.47 or later, as indicated by the vulnerability's scope to prior versions. Relevant advisories, including the VulnCheck report at https://www.vulncheck.com/advisories/wpdiscuz-before-destructive-get-action-deletes-all-comments-by-email, detail the issue, while the official plugin pages at https://wordpress.org/plugins/wpdiscuz/ and https://wordpress.org/plugins/wpdiscuz/#developers provide access to patches and developer resources.
