CVE-2025-70030 is a vulnerability corresponding to CWE-1333 (Inefficient Regular Expression Complexity, version 4.19) in Sunbird-Ed SunbirdEd-portal version 1.13.4. Published on 2026-03-09, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating a high-severity issue primarily impacting availability.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. Exploitation triggers inefficient regular expression processing, leading to a denial-of-service condition through resource exhaustion, without compromising confidentiality or integrity.
Mitigation details are available in referenced resources, including a GitHub Gist at https://gist.github.com/zcxlighthouse/d80812b9d90683c0ac65db656ae3cfb0 and the project's repositories at https://github.com/Sunbird-Ed and https://github.com/Sunbird-Ed/SunbirdEd-portal.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover inefficient regex patterns via performance or static analysis.
Development standards and tools can require safe regex construction and forbid known exponential patterns.
Denial-of-service protections limit resource exhaustion caused by expensive regex evaluation.
Input validation can constrain data that would otherwise trigger worst-case regex complexity.

Security testing can detect and reject regex patterns with exponential worst-case complexity.
Secure development lifecycle mandates review of algorithmic efficiency, directly addressing ReDoS-prone regex.
Application security requirements can specify input-validation rules that limit regex complexity.
Secure architecture principles encourage avoidance of computationally expensive constructs such as catastrophic backtracking.
Secure coding standards explicitly prohibit or limit the use of inefficient regular expressions.
