An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-106118 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- SixLabors.ImageSharp (NuGet): affected from 3.0.0; fixed in 3.2.0\n- SixLabors.ImageSharp (NuGet): affected from 3.0.0; fixed in 3.2.0\n- SixLabors.ImageSharp (NuGet): affected from 4.0.0; fixed in 4.1.1\n- SixLabors.ImageSharp (NuGet): affected from 4.0.0; fixed in 4.1.1\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-2026-106118/ (Markdown: https://insights.sbomify.com/CVE-2026-106118/index.md)","id":"CVE-2026-106118","markdown":"https://insights.sbomify.com/CVE-2026-106118/index.md","name":"CVE-2026-106118","record":{"aliases":["ECHO-9c96-4e24-b0b3","GHSA-v76p-62qx-wwq2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ImageSharp graphics library","requires_auth":"none","summary":"Attacker can trigger heap out-of-bounds writes via crafted tiled TIFF files, leading to code execution or crashes in applications using ImageSharp.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"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 3.0.0 until 4.1.1, tiled TIFF decoding allocates a destination buffer using TileWidth but TiffDecompressorsFactory.Create constructs T4, T6, and Modified Huffman decompressors using the full frame width. TiffDecoderCore.DecodeTilesChunky can therefore direct frame-width fax scanlines into a tile-width buffer when TileWidth is smaller than ImageWidth. The mismatch causes attacker-controlled out-of-bounds writes, heap corruption, and process termination even with legal per-row run codes. This tiled-path vulnerability is distinct from oversized CCITT runs in strip decoding.
