2026-07-14Fixed #37210 -- Logged cached_db session cache delete failures.vismaytiwari
2026-07-06Fixed CVE-2026-48588 -- Prevented caching of responses that set cookies and ↵Natalia
vary on Cookie. `UpdateCacheMiddleware` skipped caching `Set-Cookie` responses that vary on `Cookie` only when the request had no cookies at all. A request carrying an unrelated cookie bypassed the guard, allowing a newly-issued session cookie to be stored in Django's shared cache. The guard now applies whenever a response both sets a cookie and varies on Cookie, regardless of what cookies the incoming request carried. Thanks Chris Whyland for the report, Jake Howard for initial triage, and Jacob Walls for reviews.
2026-06-26Fixed #37191 -- Prevented ValueError in FileBasedCache.touch() for expired keys.ayoub
2026-06-24Fixed #37174 -- Used netstring delimiter between vary on arguments for ↵Jacob Walls
cached template fragments. This algorithm used a delimiter, but because it didn't use a length, argument values containing the delimiter could still cause collisions.
2026-06-24Fixed #37101 -- Used netstring delimiter between vary on headers for cached ↵Jacob Walls
pages. This prevents collisions between header values that concatenate to the same thing.
2026-06-19Refs #36560, CVE-2026-35193 -- Recognized qualified cache-control directives.Natalia
The switch from substring matching to exact token membership in 142b881cecaddc334cabec139e701c0e4b9798da caused qualified directive forms permitted by RFC 9111 (e.g. `Cache-Control: private="Set-Cookie"`) to be missed, allowing such responses to be stored in a shared cache. This work added a new `split_directive_names()` helper that yields the lowercased directive name from each token, dropping any qualified value and stripping whitespace around "=", so qualified forms reduce to their directive name. `UpdateCacheMiddleware` now uses it so `private`, `no-cache`, and `no-store` (and the `public` exception for `Authorization`) match regardless of qualified form. Aligned `ConditionalGetMiddleware.needs_etag()` to use the same helper, since it relied on the same brittle exact-token check. Sharing one helper keeps the two directive lookups consistent and means malformed input (e.g. `no-store="x"`) now correctly suppresses the `ETag` instead of being silently ignored. Also stripped whitespace around `=` in `patch_cache_control`'s directive parsing so a qualified directive with stray whitespace is still recognized. Thanks to Jacob Walls for reviews.
2026-06-09Fixed #37130 -- Skipped DB cache deletion when culling offset is zero.vishwa
2026-06-09Refs #36560, CVE-2026-35193 -- Replaced substring check on cache-control ↵Jacob Walls
directives in UpdateCacheMiddleware. Avoid false positives from hypothetical extension directives that could be superstrings of the ones we are checking.
2026-06-08Refs CVE-2026-48587 -- Added helper to properly split header values.Natalia
Extracted the repeated `split(",")` + per-token `.strip()` pattern into a `split_header_value()` generator in django/utils/http.py. The previous `cc_delim_re` regex only stripped whitespace adjacent to the comma delimiter, leaving leading or trailing whitespace on the first and last tokens. Now, `split_header_value()` strips every token fully, matching RFC 9110's optional-whitespace rules. Thanks to Shai Berger, Jacob Walls, and Sarah Boyce for reviews.
