# bug-1962: apiserver JWT excluded-path check drops the last character of every entry, matching unintended paths
|
|
|
|
## Description
|
|
**Observed:** (source reading; follow-up of the 2026-10-10 P0 fixes (bug-1936..1957))
|
|
`ValidateHandler.isExcludedPath` (`middleware/validatehandler.go:52-61`) trims the last character of every excluded entry, not only a trailing `*`, and matches by prefix: `/ping` matches any path starting with `/pin`, and `/swagger/*any` never matches.
|
|
|
|
**Expected:** Exact entries match exactly; only entries ending in `*` match by prefix.
|
|
**Impact:** Security: paths that merely share a prefix with an excluded entry skip JWT validation.
|
|
**Found by:** follow-up of the 2026-10-10 P0 fixes (bug-1936..1957)
|
|
## Environment
|
|
- OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
|
|
- libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
|
|
- Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
|
|
- Build: asan (xce.build)
|
|
- Code: scheduler-framework @ 19be145d-dirty
|
|
- Deployment: any (found by source reading; confirmed by the RED test of the fix)
|
|
|
|
## Reproduction
|
|
1. Request `/pinX` (or any route sharing the prefix) without a token: JWT validation is skipped.
|
|
- Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
|
|
- Evidence: the code sites quoted in Description; no logs kept.
