An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of RUSTSEC-2021-0158 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ammonia (crates.io): affected from 0.0.0-0; fixed in 4.1.7, 4.2.3\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/RUSTSEC-2021-0158/ (Markdown: https://insights.sbomify.com/RUSTSEC-2021-0158/index.md)","id":"RUSTSEC-2021-0158","markdown":"https://insights.sbomify.com/RUSTSEC-2021-0158/index.md","name":"RUSTSEC-2021-0158","record":{"aliases":["GHSA-f2pc-rwv3-69mv"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Rust HTML sanitizer","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript via unsanitized SVG animation tags if specific tags are explicitly allowed, requiring user interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The neutralization that ammonia applied to `animate` and `set` was not applied to other forms of SVG animation, which can be used for XSS.\n\nThe following SVG will produce a link with a javascript scheme.\nIf the user clicks this link, they will run it.\n\n```xml\n\u003csvg xmlns=\"http://www.w3.org/2000/svg\"\u003e\n  \u003ca\u003e\n    \u003canimateMotion attributeName=\"href\" to=\"javascript:alert('SET_XSS')\"\u003e\u003c/animateMotion\u003e\n    \u003ctext y=\"30\"\u003eClick set\u003c/text\u003e\n  \u003c/a\u003e\n\u003c/svg\u003e\n```\n\nAmmonia did not apply attribute filters based on `attributeName`,\nso the contents of the `to`, `from`, and `values` tags were not sanitized as URLs.\n\nApplications that do not explicitly allow any of these tags should not be affected,\nsince none are allowed by default.\n\n---\n\nThis vulnerability was reported by [ucsurf](https://uc.surf).","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"XSS in ammonia via SVG `animateMotion`, `animateTransform`, and/or `animateColor` tags","id":"RUSTSEC-2021-0158","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["4.1.7","4.2.3"],"introduced":["0.0.0-0","4.2.0"],"last_affected":[],"package":"ammonia","purl":"pkg:cargo/ammonia","source":"RUSTSEC-2021-0158"}],"products":null,"published":"2021-10-10","related":[],"sources":[{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can execute arbitrary JavaScript via unsanitized SVG animation tags if specific tags are explicitly allowed, requiring user interaction.","url":"https://insights.sbomify.com/RUSTSEC-2021-0158/"}
