Response disclosure via shared authorization-cache collision
Published Oct 17, 2024 · Updated Dec 6, 2024
Information disclosure in JetBrains Ktor before 2.3.13 allows remote attackers to read cached authenticated HTTP responses. HttpCache stored GET responses for requests carrying Authorization headers in a shared client's cache, allowing a later request for the same cache entry to receive another user's response. Exposure requires an application to install HttpCache, share one client among users, and process cacheable authenticated requests; the reported consequence is response disclosure only.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <2.3.13
- Affected versionversion=0 <3.0.0
