Any deployment using the library prior to 1.29.0 is susceptible to ReDoS when a malicious issuu_id is supplied.", "description_and_impact": "A Regular Expression Denial of Service (ReDoS) flaw was discovered in tarteaucitron.js that is triggered when processing the issuu_id parameter. The vulnerable regular expression can be fed a specially crafted value that causes the JavaScript engine to perform an exponential amount of work, leading to significant CPU usage and a potential denial of service for end users. The impact is limited to application availability; confidentiality and integrity are not directly affected.", "risk_and_exploitability": "The CVSS score of 4.4 classifies this flaw as low to moderate severity. The EPSS score of less than 1% indicates a very low likelihood of exploitation, and the vulnerability is not listed in the CISA KEV catalog. Attackers would need to provide a crafted issuu_id value, which could come from an attacker's controlled web page embedding the script or an injected request. The requirement for user-supplied input keeps the threat realistic in scenarios where the banner is exposed to untrusted input sources."}}}}, "created": "2026-01-14T11:08:29.047632+00:00", "updated": "2026-04-18T16:30:05.080494+00:00", "vendors": ["amauri", "amauri$PRODUCT$tarteaucitronjs"]}
