An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-26w7-cxv4-gfx2 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- astro (npm): affected all versions; fixed in 7.2.8\n- astro (npm): affected all versions; fixed in 7.2.8\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/GHSA-26w7-cxv4-gfx2/ (Markdown: https://insights.sbomify.com/GHSA-26w7-cxv4-gfx2/index.md)","id":"GHSA-26w7-cxv4-gfx2","markdown":"https://insights.sbomify.com/GHSA-26w7-cxv4-gfx2/index.md","name":"GHSA-26w7-cxv4-gfx2","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Astro web framework","requires_auth":"none","summary":"Remote code execution via malicious AVIF images processed by Astro's default image optimization service.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"A vulnerability in `libheif`, used by the default Sharp image service in Astro, can lead to remote code execution when a malicious AVIF image is optimized.\n\nProjects are affected when an attacker can cause Astro to process an untrusted AVIF image.\n\nThe fix was released in Astro 7.2.8, which requires Sharp 0.35.4.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Astro: Remote code execution through AVIF image optimization","id":"GHSA-26w7-cxv4-gfx2","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"npm","fixed":["7.2.8"],"introduced":["0"],"last_affected":[],"package":"astro","purl":null,"source":"GHSA-26w7-cxv4-gfx2"},{"ecosystem":"npm","fixed":["7.2.8"],"introduced":["0"],"last_affected":[],"package":"astro","purl":"pkg:npm/astro","source":"GHSA-26w7-cxv4-gfx2"}],"products":null,"published":"2026-09-08","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Remote code execution via malicious AVIF images processed by Astro's default image optimization service.","url":"https://insights.sbomify.com/GHSA-26w7-cxv4-gfx2/"}
