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-2026-28812 in the wild and no public exploit code.\n\nAffected product: Apache JSPWiki. 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-2026-28812/ (Markdown: https://insights.sbomify.com/CVE-2026-28812/index.md)","id":"CVE-2026-28812","markdown":"https://insights.sbomify.com/CVE-2026-28812/index.md","name":"CVE-2026-28812","record":{"aliases":["GHSA-3qxc-7g4v-3gm9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache JSPWiki","requires_auth":"none","summary":"Attackers can impersonate users and escalate privileges due to missing sanity checks in the user database at startup.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"jspwiki","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"UserManager lack of checks allows impersonation in Apache JSPWiki up to 2.12.3 which may allow attackers to escalate privileges.\nUsers are recommended to upgrade to version 2.12.4 or newer which fixes this issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache JSPWiki: UserManager does not sanity-check user database at startup","id":"CVE-2026-28812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache JSPWiki: JSPWiki vulnerable to JSON hijacking","id":"CVE-2026-28813"},"packages":[],"prev":{"headline":"Apache JSPWiki: Error Handling - Reveals Error Details","id":"CVE-2026-28811"},"products":["Apache JSPWiki"],"published":"2026-07-30","related":[{"cvss_score":9.1,"headline":"Arbitrary file deletion on logout","id":"CVE-2021-44140","kev_date_added":null,"published":"2021-11-24"},{"cvss_score":8.8,"headline":"Apache JSPWiki: JSPWiki vulnerable to JSON hijacking","id":"CVE-2026-28813","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":8.8,"headline":"User Group Privilege Escalation","id":"CVE-2022-34158","kev_date_added":null,"published":"2022-08-04"},{"cvss_score":8.8,"headline":"Apache JSPWiki CSRF Account Takeover","id":"CVE-2022-24947","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":7.5,"headline":"Apache JSPWiki: Error Handling - Reveals Error Details","id":"CVE-2026-28811","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":7.5,"headline":"Apache JSPWiki: Pre-Authentication Arbitrary Wiki Markup Rendering","id":"CVE-2026-28814","kev_date_added":null,"published":"2026-07-30"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-31","vendors":["Apache Software Foundation"]},"summary":"Attackers can impersonate users and escalate privileges due to missing sanity checks in the user database at startup.","url":"https://insights.sbomify.com/CVE-2026-28812/"}
