Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48920 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:email-ext (Maven): affected all versions; fixed in 1933.1935.v276319e3cc47\n- org.jenkins-ci.plugins:email-ext (Maven): affected all versions; fixed in 1933.1935.v276319e3cc47\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-2026-48920/ (Markdown: https://insights.sbomify.com/CVE-2026-48920/index.md)","id":"CVE-2026-48920","markdown":"https://insights.sbomify.com/CVE-2026-48920/index.md","name":"CVE-2026-48920","record":{"aliases":["GHSA-mq58-m26g-46gp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Email Extension Plugin","requires_auth":"low_privilege","summary":"Attackers controlling email content can read arbitrary files from the Jenkins controller filesystem by specifying file URLs in inline images.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"email_extension","vendor":"jenkins"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"Jenkins Email Extension Plugin 1933.v45cec755423f and earlier allows inlining images as `base64` in email content by setting the `data-inline` attribute, without restrictions on the image URLs that can be inlined, allowing attackers able to control the email content to specify `file:` URLs for images to read arbitrary files from the Jenkins controller filesystem.","ecosystems":["Maven"],"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":"Jenkins Email Extension Plugin: Attackers able to control email content may specify `file:` URLs for images to read arbitrary files from Jenkins controller filesystem","id":"CVE-2026-48920","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Jenkins Pipeline: Groovy Libraries Plugin does not prohibit symbolic links in shared libraries","id":"CVE-2026-48921"},"packages":[{"ecosystem":"Maven","fixed":["1933.1935.v276319e3cc47"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:email-ext","purl":null,"source":"GHSA-mq58-m26g-46gp"},{"ecosystem":"Maven","fixed":["1933.1935.v276319e3cc47"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:email-ext","purl":"pkg:maven/org.jenkins-ci.plugins/email-ext","source":"GHSA-mq58-m26g-46gp"}],"prev":{"headline":"Jenkins Active Directory Plugin deserializes data from LDAP referrals without validation","id":"CVE-2026-48919"},"products":["Jenkins Email Extension Plugin"],"published":"2026-05-27","related":[{"cvss_score":9.9,"headline":"Sandbox escape in Jenkins Email Extension Plugin","id":"CVE-2023-25765","kev_date_added":null,"published":"2023-02-15"},{"cvss_score":9.9,"headline":"Script security sandbox bypass in Jenkins Email Extension Plugin","id":"CVE-2019-1003032","kev_date_added":null,"published":"2019-03-08"},{"cvss_score":7.5,"headline":"Jenkins Email Extension Plugin SMTP password transmitted and displayed in plain text","id":"CVE-2020-2232","kev_date_added":null,"published":"2020-08-12"},{"cvss_score":6.5,"headline":"Jenkins Email Extension Plugin showed plain text SMTP password in configuration form field","id":"CVE-2018-1000176","kev_date_added":null,"published":"2018-05-08"},{"cvss_score":5.4,"headline":"Cross-site Scripting in Jenkins Email Extension Plugin","id":"CVE-2023-25763","kev_date_added":null,"published":"2023-02-15"},{"cvss_score":5.4,"headline":"Cross-site Scripting in Jenkins Email Extension Plugin","id":"CVE-2023-25764","kev_date_added":null,"published":"2023-02-15"}],"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["Jenkins Project"]},"summary":"Attackers controlling email content can read arbitrary files from the Jenkins controller filesystem by specifying file URLs in inline images.","url":"https://insights.sbomify.com/CVE-2026-48920/"}
