Any signed-in user can exploit it over the network, 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-2026-88420 exists.\n\nAffected product: n/a. 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-2026-88420/ (Markdown: https://insights.sbomify.com/CVE-2026-88420/index.md)","id":"CVE-2026-88420","markdown":"https://insights.sbomify.com/CVE-2026-88420/index.md","name":"CVE-2026-88420","record":{"aliases":["GHSA-2w4j-r762-9783"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Puput blog plugin","requires_auth":"low_privilege","summary":"Authenticated attackers with editor privileges can execute arbitrary code in victim browsers via reflected XSS in the Puput blog plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 reflected cross-site scripting (XSS) vulnerability in the EntryAbstract.save() component of APSL puput v1.2.1 through v2.2.0 allows authenticated attackers with Wagtail Editor privileges to execute arbitrary code in the context of the victim's browser via a crafted payload.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2026-88420","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in n/a","id":"CVE-2026-88421"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2026-88419"},"products":["n/a"],"published":"2026-09-25","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-29","vendors":["n/a"]},"summary":"Authenticated attackers with editor privileges can execute arbitrary code in victim browsers via reflected XSS in the Puput blog plugin.","url":"https://insights.sbomify.com/CVE-2026-88420/"}
