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-2026-48942 in the wild and no public exploit code.\n\nAffected product: getk2.org K2 extension for Joomla. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-48942/ (Markdown: https://insights.sbomify.com/CVE-2026-48942/index.md)","id":"CVE-2026-48942","markdown":"https://insights.sbomify.com/CVE-2026-48942/index.md","name":"CVE-2026-48942","record":{"aliases":["GHSA-5hmf-7m33-2v23"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla K2 extension","requires_auth":"none","summary":"Attackers can inject malicious scripts via user image fields in the K2 extension, potentially stealing sessions or executing code in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[{"product":"k2","vendor":"joomlaworks"}],"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":"K2 ≤ 2.26 renders the `#__k2_users.image` column directly into HTML `src` attributes via two distinct templates, in both cases without HTML escaping.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Joomla Extension - getk2.org - Stored-XSS in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48942","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Joomla Extension - getk2.org - Authenticated user property mass-assignment in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48943"},"packages":[],"prev":{"headline":"Joomla Extension - getk2.org - Unauthenticated folder delete in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48941"},"products":["K2 extension for Joomla"],"published":"2026-06-25","related":[{"cvss_score":9.8,"headline":"class.upload.php in verot.net omits .pht from the set of dangerous file extensions","id":"CVE-2019-19634","kev_date_added":null,"published":"2019-12-17"},{"cvss_score":9.8,"headline":"Remote code execution in verot/class.upload.php","id":"CVE-2019-19576","kev_date_added":null,"published":"2019-12-04"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2018-7482","kev_date_added":null,"published":"2018-02-28"},{"cvss_score":6.5,"headline":"Joomla Extension - getk2.org - Unauthenticated folder delete in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48941","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":6.5,"headline":"Joomla Extension - getk2.org - Authenticated user property mass-assignment in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48943","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":6.5,"headline":"Joomla Extension - getk2.org - Exposure of sensitive files via attachment copy in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48944","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":6.3,"headline":"Joomla Extension - getk2.org - Privileged RCE vulnerability in K2 extension for Joomla \u003c 2.26","id":"CVE-2026-48946","kev_date_added":null,"published":"2026-06-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-06-28","vendors":["getk2.org"]},"summary":"Attackers can inject malicious scripts via user image fields in the K2 extension, potentially stealing sessions or executing code in victim browsers.","url":"https://insights.sbomify.com/CVE-2026-48942/"}
