CVE-2025-70030
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue pertaining to CWE-1333: Inefficient Regular Expression Complexity (4.19) was discovered in Sunbird-Ed SunbirdEd-portal v1.13.4.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA regular expression denial of service (ReDoS) vulnerability (CWE-1333) exists in SunbirdEd-portal v1.13.4 where inefficient regular expression complexity can be exploited to cause excessive resource consumption, potentially leading to service unavailability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SunbirdEd Portal versionCheck the installed version of SunbirdEd Portal by inspecting package.json, version file, or running: grep -r 'version' in the application root or check the about/admin panel if availableAffected if The installed version is exactly 1.13.4
-
Locate the vulnerable regular expression patternSearch the codebase for inefficient regex patterns that could cause catastrophic backtracking. Look for complex patterns with nested quantifiers (e.g., (a+)+, (a*)*) in source files, particularly in input validation or text processing modulesAffected if A complex regex with nested quantifiers or alternation is found in the codebase at version 1.13.4
-
Verify the vulnerable regex is activeDetermine if the identified inefficient regex is actually used in active code paths. Check if it processes user-controlled input through API endpoints, search functions, or data parsing routinesAffected if The inefficient regex processes external input and is reachable without authentication or with standard user access
You are affected if SunbirdEd Portal version 1.13.4 is running AND an inefficient regex with nested quantifiers exists in active code processing user input

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataIdentify and refactor the inefficient regular expression to eliminate catastrophic backtracking, typically by simplifying the pattern, using atomic groups, or replacing with a more efficient matching approach.
