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-2026-18356 in the wild and no public exploit code.\n\nAffected product: Unknown Limit Login Attempts Security. 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-2026-18356/ (Markdown: https://insights.sbomify.com/CVE-2026-18356/index.md)","id":"CVE-2026-18356","markdown":"https://insights.sbomify.com/CVE-2026-18356/index.md","name":"CVE-2026-18356","record":{"aliases":["GHSA-pr5g-gw8g-vfpm"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can bypass login restrictions by using case variants or email addresses, allowing blocked accounts to authenticate.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-184","name":"Incomplete List of Disallowed Inputs"}],"description":"The Limit Login Attempts Reloaded WordPress plugin before 3.3.5 does not compare logins against its username denylist case-insensitively and does not account for the account's email address, allowing an account an administrator intended to block from logging in to authenticate anyway.","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":"Limit Login Attempts Reloaded \u003c 3.3.5 - Username Denylist Bypass via Case Variant and Account Email","id":"CVE-2026-18356","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":"WPC Order Tip for WooCommerce \u003c 3.3.1 - Unauthenticated Order Data Disclosure","id":"CVE-2026-18357"},"packages":[],"prev":{"headline":"Memory corruption in Red Hat Directory Server 11.5 E4S for RHEL 8","id":"CVE-2026-18355"},"products":["Limit Login Attempts Security"],"published":"2026-08-21","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":"2026-08-21","vendors":["Unknown"]},"summary":"Attackers can bypass login restrictions by using case variants or email addresses, allowing blocked accounts to authenticate.","url":"https://insights.sbomify.com/CVE-2026-18356/"}
