Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88828 in the wild and no public exploit code.\n\nAffected product: Unknown Blacklist Manager. 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-2026-88828/ (Markdown: https://insights.sbomify.com/CVE-2026-88828/index.md)","id":"CVE-2026-88828","markdown":"https://insights.sbomify.com/CVE-2026-88828/index.md","name":"CVE-2026-88828","record":{"aliases":["GHSA-gg4x-5759-6rq2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Blocked users can bypass restrictions and authenticate via XML-RPC or Application Passwords in the Blacklist Manager for WooCommerce plugin.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"The Blacklist Manager for WooCommerce WordPress plugin from 1.3.0 to 2.3.1 does not enforce its user blocking on every authentication path, allowing the holder of an account the site owner has blocked to keep authenticating with that account's privileges, without the block being enforced or recorded.","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":"Blacklist Manager for WooCommerce 1.3.0 - 2.3.1 - Blocked User Restriction Bypass via XML-RPC and Application Passwords","id":"CVE-2026-88828","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":"Busybox: busybox: http request smuggling via pipelined requests in httpd reverse proxy","id":"CVE-2026-88829"},"packages":[],"prev":{"headline":"Disable Users \u003c= 1.0.5 - Disabled Account Authentication Bypass via XML-RPC and Application Passwords","id":"CVE-2026-88827"},"products":["Blacklist Manager"],"published":"2026-09-28","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":"2026-09-28","vendors":["Unknown"]},"summary":"Blocked users can bypass restrictions and authenticate via XML-RPC or Application Passwords in the Blacklist Manager for WooCommerce plugin.","url":"https://insights.sbomify.com/CVE-2026-88828/"}
