An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74253 in the wild and no public exploit code.\n\nAffected product: regularlabs.com Sourcerer 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-2026-74253/ (Markdown: https://insights.sbomify.com/CVE-2026-74253/index.md)","id":"CVE-2026-74253","markdown":"https://insights.sbomify.com/CVE-2026-74253/index.md","name":"CVE-2026-74253","record":{"aliases":["GHSA-23wq-9cpv-vp32"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla extension","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code via reflected user input in the Sourcerer extension for Joomla.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Joomla Extension - regularlabs.com - Unauthenticated RCE through unverified reflected user input in Sourcerer \u003c 16.0.0 - Regular Labs Sourcerer before 16.0.0 processes {source} blocks found in Joomla’s final rendered HTML without reliably determining where that code originated.","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 - regularlabs.com - Unauthenticated RCE through unverified reflected user input in Sourcerer \u003c 16.0.0","id":"CVE-2026-74253","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Joomla Extension - joomlack.fr - SQL injection in Page Builder CK \u003c 3.6.5","id":"CVE-2026-74254"},"packages":[],"prev":{"headline":"Joomla Extension - j2commerce.com - Stored XSS in Guest checkout in J2Store 1.0.0-3.3.20, 4.0.0-4.0.20, 4.1.0-4.1.5","id":"CVE-2026-74252"},"products":["Sourcerer extension for Joomla"],"published":"2026-08-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-26","vendors":["regularlabs.com"]},"summary":"Unauthenticated attackers can execute arbitrary code via reflected user input in the Sourcerer extension for Joomla.","url":"https://insights.sbomify.com/CVE-2026-74253/"}
