Sensitive-data disclosure via cached authenticated responses
Published Sep 28, 2022 · Updated May 21, 2025
Improper cache control in IKUS Software Rdiffweb before 2.4.8 allows physically proximate attackers to read sensitive account data. The secure_headers response hook omits Cache-Control, Pragma, and Expires protections from dynamic pages, allowing browsers to retain authenticated content. Exploitation requires access to a browser previously used for a signed-in session; the reported consequence is disclosure of cached data, not modification or service interruption.
