- Summary
- Inefficient Regular Expression Complexity in v8n
- Details
-
v8n is a javascript validation library. Versions of v8n prior to 1.5.1 were found to have an inefficient regular expression complexity in the
lowercase()anduppercase()regex which could lead to a denial of service attack. In testing of thelowercase()function a payload of 'a' + 'a'.repeat(i) + 'A' with 32 leading characters took 29443 ms to execute. The same issue happens with uppercase(). Users are advised to upgrade. There are no known workarounds for this issue. - Database specific
