Unauthenticated service interruption via inefficient regular expression
Published Mar 9, 2026 · Updated Mar 9, 2026
Regular expression denial of service in Sunbird-Ed SunbirdEd-portal 1.13.4 allows remote attackers to interrupt service via crafted input. The public advisory does not identify the affected expression, its code location, or the input field passed to it; it states only that malicious input causes excessive resource consumption. No authentication or user interaction is required, and the documented consequence is availability loss rather than data disclosure or modification.
