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-2026-27612 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- repostat (npm): affected all versions; fixed in 1.0.1\n- repostat (npm): affected all versions; fixed in 1.0.1\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-2026-27612/ (Markdown: https://insights.sbomify.com/CVE-2026-27612/index.md)","id":"CVE-2026-27612","markdown":"https://insights.sbomify.com/CVE-2026-27612/index.md","name":"CVE-2026-27612","record":{"aliases":["GHSA-fm8c-6m29-rp6j"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"React component library","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in user browsers via unsanitized repository names in the Repostat React component.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"repostat","vendor":"denpiligrim"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Repostat is a React component to fetch and display GitHub repository info. Prior to version 1.0.1, the `RepoCard` component is vulnerable to Reflected Cross-Site Scripting (XSS). The vulnerability occurs because the component uses React's `dangerouslySetInnerHTML` to render the repository name (`repo` prop) during the loading state without any sanitization. If a developer using this package passes unvalidated user input directly into the `repo` prop (for example, reading it from a URL query parameter), an attacker can execute arbitrary JavaScript in the context of the user's browser. In version 1.0.1, the use of dangerouslySetInnerHTML has been removed, and the repo prop is now safely rendered using standard React JSX data binding, which automatically escapes HTML entities.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Repostat Vulnerable to Reflected Cross-Site Scripting (XSS) via repo prop in RepoCard","id":"CVE-2026-27612","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"CGI Parameter Injection (Bypass of STRICT_CGI_PARAMS and EscapeShellParam)","id":"CVE-2026-27613"},"packages":[{"ecosystem":"npm","fixed":["1.0.1"],"introduced":["0"],"last_affected":[],"package":"repostat","purl":null,"source":"GHSA-fm8c-6m29-rp6j"},{"ecosystem":"npm","fixed":["1.0.1"],"introduced":["0"],"last_affected":[],"package":"repostat","purl":"pkg:npm/repostat","source":"GHSA-fm8c-6m29-rp6j"}],"prev":{"headline":"FileBrowser Quantum: Password Protection Not Enforced on Shared File Links","id":"CVE-2026-27611"},"products":["repostat"],"published":"2026-02-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["denpiligrim"]},"summary":"Attackers can execute arbitrary JavaScript in user browsers via unsanitized repository names in the Repostat React component.","url":"https://insights.sbomify.com/CVE-2026-27612/"}
