An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-25849 exists.\n\nAffected packages and fixed versions:\n- joyqi/hyper-down (Packagist): affected all versions up to 2.4.27; no fix listed\n- joyqi/hyper-down (Packagist): affected all versions up to 2.4.27; no fix listed\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-2022-25849/ (Markdown: https://insights.sbomify.com/CVE-2022-25849/index.md)","id":"CVE-2022-25849","markdown":"https://insights.sbomify.com/CVE-2022-25849/index.md","name":"CVE-2022-25849","record":{"aliases":["GHSA-4r9g-w48q-8jwm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP markdown parser","requires_auth":"none","summary":"An attacker can inject malicious scripts via the href attribute in markdown parsing, potentially executing code in the victim's browser.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"hyperdown","vendor":"hyperdown_project"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The package joyqi/hyper-down from 0.0.0 are vulnerable to Cross-site Scripting (XSS) because the module of parse markdown does not filter the href attribute very well.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site Scripting (XSS)","id":"CVE-2022-25849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2022"},"n_packages":2,"n_references":1,"next":{"headline":"Server-side Request Forgery (SSRF)","id":"CVE-2022-25850"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.4.27"],"package":"joyqi/hyper-down","purl":null,"source":"GHSA-4r9g-w48q-8jwm"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.4.27"],"package":"joyqi/hyper-down","purl":"pkg:composer/joyqi/hyper-down","source":"GHSA-4r9g-w48q-8jwm"}],"prev":{"headline":"Directory Traversal","id":"CVE-2022-25848"},"products":["joyqi/hyper-down"],"published":"2022-10-26","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-09","vendors":["n/a"]},"summary":"An attacker can inject malicious scripts via the href attribute in markdown parsing, potentially executing code in the victim's browser.","url":"https://insights.sbomify.com/CVE-2022-25849/"}
