An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66293 exists.\n\nAffected product: Libpng Libpng. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-66293/ (Markdown: https://insights.sbomify.com/CVE-2025-66293/index.md)","id":"CVE-2025-66293","markdown":"https://insights.sbomify.com/CVE-2025-66293/index.md","name":"CVE-2025-66293","record":{"aliases":["ALPINE-CVE-2025-66293","AZL-71246","AZL-71455","AZL-71458","AZL-71461","AZL-71464","AZL-71467","AZL-71470","AZL-71485","AZL-71488","AZL-71491","AZL-71494","AZL-71497","AZL-71644","BELL-CVE-2025-66293","CLSA-2026-1768212418","DEBIAN-CVE-2025-66293","ECHO-91c2-e6d0-2b32","GHSA-9mpm-9pxh-mg4f","JLSEC-2026-6","MGASA-2025-0323","MINI-x659-r72g-8hc3","OESA-2026-1124","OESA-2026-1125","OESA-2026-1126","OESA-2026-1127","OESA-2026-1128","OESA-2026-1129","ROOT-OS-ALPINE-315-CVE-2025-66293","SUSE-SU-2026:0085-1","UBUNTU-CVE-2025-66293","openSUSE-SU-2025:15801-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PNG image library","requires_auth":"none","summary":"An out-of-bounds read in libpng allows attackers to read memory beyond buffer limits when processing valid PNG images with transparency and gamma correction.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"libpng","vendor":"libpng"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files.
