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 CVE-2026-66353 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- doggo (Hex): affected from 0.1.0; fixed in 0.14.8\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/CVE-2026-66353/ (Markdown: https://insights.sbomify.com/CVE-2026-66353/index.md)","id":"CVE-2026-66353","markdown":"https://insights.sbomify.com/CVE-2026-66353/index.md","name":"CVE-2026-66353","record":{"aliases":["EEF-CVE-2026-66353","GHSA-w9rp-cf93-86pj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Elixir HTML library","requires_auth":"none","summary":"Reflected XSS in Doggo library allows attackers to inject scripts via date fields, potentially leading to code execution in web applications using the library.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in woylie doggo allows Reflected XSS.\n\nDoggo.normalize_value/2 in lib/doggo.ex returned date field values wrapped in {:safe, ...}, the Phoenix.HTML marker meaning \"already escaped, emit verbatim\", without escaping them, so the value reached the value attribute of the \u003cinput\u003e rendered by the field component unchanged.
