The AcyMailing - An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'alignment' attribute in all versions up to, and including, 10.10.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored Cross-Site Scripting in the AcyMailing WordPress newsletter plugin (all versions up to and including 10.10.2) permits authenticated contributors to inject persistent arbitrary scripts via the unsanitized 'alignment' attribute across both the classic form builder and Gutenberg block editor code paths. Any user - including unauthenticated site visitors - who subsequently loads a page containing the injected element triggers script execution in their browser, enabling session hijacking, credential theft, or malicious redirects. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to possess a valid WordPress account at contributor level or above - this is the definitive gating condition and the primary limit on real-world exposure. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 6.4 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) reflects a low-privilege network attack with scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a contributor-level WordPress account on the target site and edits or creates an AcyMailing newsletter form or Gutenberg block, injecting a crafted JavaScript payload into the 'alignment' attribute field (e.g., a value containing a script tag or event handler). The payload is stored in the database without sanitization via the vulnerable code paths in form.php or Gutenberg.php. … |
