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-2025-67290 exists.\n\nAffected packages and fixed versions:\n- Piranha (NuGet): affected all versions up to 12.0.0; no fix listed\n- Piranha (NuGet): affected all versions up to 12.0.0; 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-2025-67290/ (Markdown: https://insights.sbomify.com/CVE-2025-67290/index.md)","id":"CVE-2025-67290","markdown":"https://insights.sbomify.com/CVE-2025-67290/index.md","name":"CVE-2025-67290","record":{"aliases":["GHSA-fw48-7qf9-455m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Piranha CMS","requires_auth":"none","summary":"Attackers can execute arbitrary scripts via stored XSS in the Page Settings Excerpt field of Piranha CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"piranha_cms","vendor":"dotnetfoundation"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","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":"A stored cross-site scripting (XSS) vulnerability in the Page Settings module of Piranha CMS v12.1 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Excerpt field.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Piranha has stored cross-site scripting (XSS) vulnerability","id":"CVE-2025-67290","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"xss","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"Piranha has stored cross-site scripting (XSS) vulnerability","id":"CVE-2025-67291"},"packages":[{"ecosystem":"NuGet","fixed":[],"introduced":["0"],"last_affected":["12.0.0"],"package":"Piranha","purl":null,"source":"GHSA-fw48-7qf9-455m"},{"ecosystem":"NuGet","fixed":[],"introduced":["0"],"last_affected":["12.0.0"],"package":"Piranha","purl":"pkg:nuget/Piranha","source":"GHSA-fw48-7qf9-455m"}],"prev":{"headline":"File upload in n/a","id":"CVE-2025-67289"},"products":["n/a"],"published":"2025-12-22","related":[{"cvss_score":8.1,"headline":"Piranha CMS - Site-wide Cross-Site Request Forgery (CSRF)","id":"CVE-2021-25976","kev_date_added":null,"published":"2021-11-16"},{"cvss_score":6.8,"headline":"PiranhaCMS stored XSS","id":"CVE-2025-57692","kev_date_added":null,"published":"2025-09-26"},{"cvss_score":6.1,"headline":"Piranha has stored cross-site scripting (XSS) vulnerability","id":"CVE-2025-67291","kev_date_added":null,"published":"2025-12-22"},{"cvss_score":6.1,"headline":"Piranha CMS vulnerable to stored cross-site scripting (XSS)","id":"CVE-2025-61413","kev_date_added":null,"published":"2025-10-23"},{"cvss_score":5.4,"headline":"Piranha CMS - Stored XSS in Page Title","id":"CVE-2021-25977","kev_date_added":null,"published":"2021-10-25"},{"cvss_score":4.7,"headline":"Piranha CMS Cross-site Scripting vulnerability","id":"CVE-2024-55341","kev_date_added":null,"published":"2024-12-20"}],"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":"2026-07-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts via stored XSS in the Page Settings Excerpt field of Piranha CMS.","url":"https://insights.sbomify.com/CVE-2025-67290/"}
