{"answers":{"affected":"5 open source packages ship an affected version, including github.com/imgproxy/imgproxy/v3, github.com/imgproxy/imgproxy and github.com/imgproxy/imgproxy/v2.","exploited":"There is no known exploitation of CVE-2026-123615 in the wild and no public exploit code.","exposure":"","fix":"Upgrade github.com/imgproxy/imgproxy/v3 to 4.0.17 or later.","what":"CVE-2026-123615 is a high-severity vulnerability in imgproxy, published on 8 Nov 2026."},"fix_prompt":"Check this codebase for CVE-2026-123615 and fix it if it is affected.\n\nWhat it is: CVE-2026-123615 is a high-severity vulnerability in imgproxy, published on 8 Nov 2026. \nExploitation: There is no known exploitation of CVE-2026-123615 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/imgproxy/imgproxy/v3 (Go): affected from 3.3.0; no fix listed\n- github.com/imgproxy/imgproxy/v3 (Go): affected from 3.3.0; fixed in 4.0.17\n- github.com/imgproxy/imgproxy (Go): affected all versions; no fix listed\n- github.com/imgproxy/imgproxy/v2 (Go): affected all versions; no fix listed\n- github.com/imgproxy/imgproxy/v4 (Go): affected all versions; fixed in 4.0.17\n\nTask:\n1. 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-2026-123615/ (Markdown: https://insights.sbomify.com/CVE-2026-123615/index.md)","id":"CVE-2026-123615","markdown":"https://insights.sbomify.com/CVE-2026-123615/index.md","name":"CVE-2026-123615","record":{"aliases":["GHSA-494m-4556-wf5p","GHSA-c4x5-qr47-7gw4","GO-2026-6895"],"analysis":null,"analysis_generated_by":null,"assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"imgproxy 3.3.0 before 4.0.17 contains an out-of-bounds heap read and write in the ICO loader's BMP header reconstruction (vips_foreign_load_ico_header in vips/icoload.c) when an ICO entry declares a tiny data size, causing unvalidated header fields to be read and written past the allocated buffer.
