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-2026-77609 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mediawiki/semantic-media-wiki (Packagist): affected all versions; fixed in 7.2.0\n- mediawiki/semantic-media-wiki (Packagist): affected all versions; fixed in 7.2.0\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-2026-77609/ (Markdown: https://insights.sbomify.com/CVE-2026-77609/index.md)","id":"CVE-2026-77609","markdown":"https://insights.sbomify.com/CVE-2026-77609/index.md","name":"CVE-2026-77609","record":{"aliases":["GHSA-hw3m-8j5x-94ff"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki extension","requires_auth":"none","summary":"An open redirect in Semantic MediaWiki allows attackers to redirect users to malicious sites via crafted subpages, facilitating phishing attacks.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"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-601","name":"URL Redirection to Untrusted Site"}],"description":"Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages. Prior to version 7.2.0, `Special:URIResolver` resolves its user-controlled subpage to a MediaWiki title and issues an HTTP 303 redirect to `$title-\u003egetFullURL()` without validating the resolved target. A crafted subpage can make that target point off-host: an interwiki prefix redirects to the foreign wiki (for example `Special:URIResolver/mw-3AFoo`, which decodes to `mw:Foo`, redirects to `https://www.mediawiki.org/wiki/Foo`), and where the resolved URL carries an authority the target can even embed `user:pass@host` credentials. The result is an open redirect to an attacker-influenced host, usable for phishing from a trusted wiki URL. Version 7.2.0 fixes the issue.","ecosystems":["Packagist"],"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":"Semantic MediaWiki has an open redirect in Special:URIResolver","id":"CVE-2026-77609","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Semantic MediaWiki has a query debug output XSS (`DebugFormatter`)","id":"CVE-2026-77610"},"packages":[{"ecosystem":"Packagist","fixed":["7.2.0"],"introduced":["0"],"last_affected":[],"package":"mediawiki/semantic-media-wiki","purl":null,"source":"GHSA-hw3m-8j5x-94ff"},{"ecosystem":"Packagist","fixed":["7.2.0"],"introduced":["0"],"last_affected":[],"package":"mediawiki/semantic-media-wiki","purl":"pkg:composer/mediawiki/semantic-media-wiki","source":"GHSA-hw3m-8j5x-94ff"}],"prev":{"headline":"Semantic MediaWiki has reflected XSS in `Special:SearchByProperty` (`property` and `value` parameters)","id":"CVE-2026-77608"},"products":["SemanticMediaWiki"],"published":"2026-09-18","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":"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":"2026-09-22","vendors":["SemanticMediaWiki"]},"summary":"An open redirect in Semantic MediaWiki allows attackers to redirect users to malicious sites via crafted subpages, facilitating phishing attacks.","url":"https://insights.sbomify.com/CVE-2026-77609/"}
