Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GPTCache versions up to and including 0.1.44 are affected. An attacker with local access who can supply crafted file or image input can cause different inputs to produce colliding cache keys, because the key is built from only the buffered prefix of the data. The source describes the attack as high complexity and difficult to exploit, and says a public exploit exists. No fixed version is listed.
