Vulnerability from gsd
Modified
2022-12-13 00:00
Details
## Summary Loofah `>= 2.2.0, < 2.19.1` uses recursion for sanitizing `CDATA` sections, making it susceptible to stack exhaustion and raising a `SystemStackError` exception. This may lead to a denial of service through CPU resource consumption. ## Mitigation Upgrade to Loofah `>= 2.19.1`. Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized.
