Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-123776/ (Markdown: https://insights.sbomify.com/CVE-2026-123776/index.md)","id":"CVE-2026-123776","markdown":"https://insights.sbomify.com/CVE-2026-123776/index.md","name":"CVE-2026-123776","record":{"aliases":["GHSA-vx75-vp6j-73h2"],"analysis":null,"analysis_generated_by":null,"assigner":"CPANSec","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1287","name":"Improper Validation of Specified Type of Input"}],"description":"RRD::CGI::Image versions through 0.01 for Perl pass CGI query parameters containting \"tz\" to tzset(), , so a FIFO or device path blocks the CGI process.\n\nThe normalize_params method sends any query key matching /tz/i to tz(), which sets $ENV{TZ} to that value, with no validation.
