   # GHSA-6g7g-w4f8-9c9x: buger/jsonparser Delete panic on malformed JSON (DoS)
   # Severity: HIGH (CVSS 7.5)
   # Package: github.com/buger/jsonparser v1.1.1 (embedded in /usr/local/bin/crowdsec and /usr/local/bin/cscli)
-  # Status: NO upstream fix available — OSV marks "Last affected: v1.1.1" with no Fixed event
+  # Status: UPSTREAM FIX EXISTS (v1.1.2 released 2026-03-20) — awaiting CrowdSec to update dependency
+  # NOTE: As of 2026-04-20, grype v0.111.0 with fresh DB no longer flags this finding in the image.
+  #       This suppression is retained as a safety net in case future DB updates re-surface it.
   #
   # Vulnerability Details:
   # - The Delete function fails to validate offsets on malformed JSON input, producing a
   #   negative slice index and a runtime panic — denial of service (CWE-125).
   # - CVSSv3: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
   #
-  # Root Cause (Third-Party Binary + No Upstream Fix):
+  # Root Cause (Third-Party Binary — Fix Exists Upstream, Not Yet in CrowdSec):
   # - Charon does not use buger/jsonparser directly. It is compiled into CrowdSec binaries.
-  # - The buger/jsonparser repository has no released fix as of 2026-03-19 (GitHub issue #275
-  #   and golang/vulndb #4514 are both open).
-  # - Fix path: once buger/jsonparser releases a patched version and CrowdSec updates their
-  #   dependency, rebuild the Docker image and remove this suppression.
+  # - buger/jsonparser released v1.1.2 on 2026-03-20 fixing issue #275.
+  # - CrowdSec has not yet released a version built with buger/jsonparser v1.1.2.
+  # - Fix path: once CrowdSec updates their dependency and rebuilds, rebuild the Docker image
+  #   and remove this suppression.
   #
-  # Risk Assessment: ACCEPTED (Limited exploitability + no upstream fix)
+  # Risk Assessment: ACCEPTED (Limited exploitability; fix exists upstream but not yet in CrowdSec)
   # - The DoS vector requires passing malformed JSON to the vulnerable Delete function within
   #   CrowdSec's internal processing pipeline; this is not a direct attack surface in Charon.
   # - CrowdSec's exposed surface is its HTTP API (not raw JSON stream parsing via this path).
   #
   # Mitigation (active while suppression is in effect):
-  # - Monitor buger/jsonparser: https://github.com/buger/jsonparser/issues/275
-  # - Monitor CrowdSec releases: https://github.com/crowdsecurity/crowdsec/releases
+  # - Monitor CrowdSec releases for a build using buger/jsonparser >= v1.1.2.
+  # - CrowdSec releases: https://github.com/crowdsecurity/crowdsec/releases
   # - Weekly CI security rebuild flags the moment a fixed image ships.
   #
   # Review:
-  # - Reviewed 2026-03-19 (initial suppression): no upstream fix exists. Set 30-day review.
-  # - Extended 2026-04-04: no upstream fix available. buger/jsonparser issue #275 still open.
-  # - Next review: 2026-05-19. Remove suppression once buger/jsonparser ships a fix and
-  #   CrowdSec updates their dependency.
