Description Matteo Signorini 2026-09-02 14:03:06 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.

Comment 1 Rodolfo Olivieri 2026-09-02 17:41:18 UTC
Goose is not affected by this CVE, as the results are matching only the ui and documentation. In this case, both are removed in our specfile¹, since they are either used to compose the webui (desktop version) or documentation.
