CVE-2026-25331: Activity Log <= 5.5.4 – Authenticated (Contributor+) Stored Cross-Site Scripting (wp-security-audit-log)

CVE ID CVE-2026-25331
Plugin wp-security-audit-log
Severity Medium (CVSS 6.4)
CWE 79
Vulnerable Version 5.5.4
Patched Version 5.6.0
Disclosed February 13, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-25331:
The Activity Log plugin for WordPress, versions up to and including 5.5.4, contains an authenticated stored cross-site scripting (XSS) vulnerability. The vulnerability exists in the plugin’s alert formatter component, which fails to properly escape JavaScript output in certain administrative interface links. This allows attackers with contributor-level or higher permissions to inject arbitrary scripts that execute when an administrator views the activity log.

The root cause is insufficient output escaping in the `Alert_Formatter::format_meta` method within `/wp-security-audit-log/classes/Helpers/formatters/class-alert-formatter.php`. Specifically, when processing the `%MetaLink%` placeholder (lines 62-71 in the patched version), the plugin constructs an HTML anchor tag with an `onclick` handler that directly incorporates user-controlled metadata values without proper escaping. The vulnerable code uses `$value` directly in the JavaScript context without applying `esc_js()` to the `$value` variable before inserting it into the `onclick` attribute.

An attacker with contributor privileges can exploit this vulnerability by triggering specific WordPress events that generate activity log entries with malicious metadata. The attacker would craft payloads containing JavaScript code within custom field values or other metadata that eventually populates the `%MetaLink%` formatter. When an administrator views the activity log page (`/wp-admin/admin.php?page=wsal-auditlog`), the malicious script executes in the administrator’s browser context, allowing session hijacking, privilege escalation, or site compromise.

The patch adds proper escaping by calling `esc_js($value)` before using the value in the JavaScript context. In the patched version at line 67, the code now reads `$escaped_value = esc_js( $value );` and uses `$escaped_value` in the `onclick` handler. This ensures that any special JavaScript characters in the user-controlled metadata are properly encoded, preventing script injection while maintaining the functionality of the exclusion link.

Successful exploitation allows authenticated attackers with contributor-level access to execute arbitrary JavaScript in administrator sessions. This can lead to session theft, administrative account takeover, site defacement, malware injection, or data exfiltration. The CVSS score of 6.4 reflects the need for authentication but the high impact of compromising administrative accounts in a WordPress environment.
