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-2026-107887/ (Markdown: https://insights.sbomify.com/CVE-2026-107887/index.md)","id":"CVE-2026-107887","markdown":"https://insights.sbomify.com/CVE-2026-107887/index.md","name":"CVE-2026-107887","record":{"aliases":["GHSA-q8c9-qpq5-4xhg"],"analysis":null,"analysis_generated_by":null,"assigner":"WPScan","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Advanced Twenty Seventeen WordPress plugin through 1.3.1 does not perform any capability or nonce check on the action that creates and activates its bundled child , allowing any authenticated user such as a subscriber to switch the site's active  site-wide, and allowing the same action to be triggered against any logged-in user including an administrator via CSRF.","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":"Advanced Twenty Seventeen \u003c= 1.3.1 - Subscriber+ Site Theme Switch via ats_create_child_theme","id":"CVE-2026-107887","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in CUPS","id":"CVE-2026-107888"},"packages":[],"prev":{"headline":"Use after free in CUPS","id":"CVE-2026-107886"},"products":["Advanced Twenty Seventeen"],"published":"2026-10-24","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-24","vendors":["Unknown"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-107887/"}
