An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-106110 exists.\n\nAffected packages and fixed versions:\n- SixLabors.ImageSharp (NuGet): affected from 2.0.0; fixed in 3.2.0\n- SixLabors.ImageSharp (NuGet): affected from 2.0.0; fixed in 3.2.0\n- SixLabors.ImageSharp (NuGet): affected from 4.0.0; fixed in 4.1.2\n- SixLabors.ImageSharp (NuGet): affected from 4.0.0; fixed in 4.1.2\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-2026-106110/ (Markdown: https://insights.sbomify.com/CVE-2026-106110/index.md)","id":"CVE-2026-106110","markdown":"https://insights.sbomify.com/CVE-2026-106110/index.md","name":"CVE-2026-106110","record":{"aliases":["ECHO-7a33-eca5-f033","GHSA-j9gm-c75j-xc9q"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ImageSharp graphics library","requires_auth":"none","summary":"An attacker can cause memory corruption and process termination in ImageSharp by triggering a buffer overflow in the TIFF CCITT T4 encoder.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"imagesharp","vendor":"sixlabors"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"ImageSharp is a 2D graphics library. From 2.0.0 until 4.1.2, the TIFF CCITT Group 3 encoder allocates an undersized compressed-data buffer for narrow 1-bit images. TiffCcittCompressor.Initialize does not reserve enough space for the row data and T4 end-of-line codes, and T4BitCompressor.CompressStrip reaches unchecked writes when TiffCompression.CcittGroup3Fax is selected directly or inherited from decoded TIFF metadata. An attacker-controlled encode or decode-and-re-encode flow can write beyond the logical output span, corrupt process memory, and terminate the process.
