Vulnerability details
The vulnerability allows a remote attacker to cause applications to resolve relative references to unintended resources or treat distinct references as equivalent.
The vulnerability exists due to improper resolution of path equivalence in fast-uri's normalize() and serialize() functions when dot-segment removal is applied to relative references before resolution. A remote attacker can supply references such as 'a/../b' or '../x', normalized to '/b' or 'x', to escape intended directories or interfere with cache, deduplication, or authorization keys.
