This vulnerability involves inefficient regular expression complexity in Sunbird-Ed SunbirdEd-portal v1.13.4, classified under CWE-1333. The CVSS 3.1 base score is 7.5 (high), with network attack vector, low attack complexity, no privileges or user interaction required, and impacts availability only. The inefficient regex can be exploited remotely to cause denial of service by resource exhaustion. No patch or official remediation information is provided in the available data.

The vulnerability impacts the availability of the affected system by enabling denial of service through inefficient regular expression processing. It does not affect confidentiality or integrity. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider applying temporary mitigations such as limiting input size or request rate to reduce potential impact from regex-based denial of service attempts.
