medium Nessus Plugin ID 331798
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Prior to 8.5.19, if from is unset, an attacker can cause PreviousMap.loadFile() to read an unintended source-map file by supplying an absolute or directory- traversal sourceMappingURL. The resulting map's sources and sourcesContent may then be exposed to the application. This issue is fixed in version 8.5.19. (CVE-2026-69153)
Note that Nessus relies on the presence of the package as reported by the vendor.
