CVE-2022-25881
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
http-cache-semantics versions prior to 4.1.1
Description
The issue can be exploited via malicious request header values sent to a server, when that server reads the cache policy from the request using this library. This leads to a Denial of Service due to an Inefficient Regular Expression Complexity.
Recommendations
For versions prior to 4.1.1, update to version 4.1.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the library until a patch is applied. Avoid using the library to read cache policies from requests with potentially malicious header values until the issue is resolved.
