Unauthenticated Cross Site Scripting (XSS) in Anti Spam and list cleaner – AcyChecker <= 1.8.1 versions.
AnalysisAI
Cross-site scripting (XSS) in the AcyChecker WordPress plugin allows attackers with low-privileged access (e.g., subscriber) to inject malicious scripts into admin pages. No public exploit code or active exploitation has been reported, and the absence of KEV and EPSS data suggests low current risk.

Vulnerability AssessmentAI
| Exploitation | Based on the CVSS vector, exploitation requires a low‑privileged WordPress user account (PR:L) and victim interaction (UI:R) - the administrator must perform an action that triggers the script. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 3.1 base score is 6.5 (Medium), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low‑privileged WordPress account (e.g., subscriber) injects a malicious JavaScript payload into a vulnerable field. When an administrator views the affected page, the script executes, potentially stealing session cookies or performing actions on behalf of the admin. … |
| Remediation | Update the AcyChecker plugin to version 1.8.2 or later, which contains the fix per the Patchstack advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
