Summary

# Broken Path Sanitization in spacecookie Library

The spacecookie library exposes the functions `sanitizePath` and `sanitizeIfNotUrl` intended to remove `..` components from paths which can be used to prevent path traversal attacks. Due to erroneous comparison code, this elimination is not actually performed which has been remedied in version 1.0.0.3 by properly comparing using `equalFilePath`.

Any user of those respective functions of any version of spacecookie should upgrade to 1.0.0.3 or later. Note that the spacecookie server executable included in the same package is not affected by the problem since a separate check would reject any malicious path that gets by `sanitizePath`.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
