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-2026-88798 in the wild and no public exploit code.\n\nAffected product: Unknown Really Simple 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-2026-88798/ (Markdown: https://insights.sbomify.com/CVE-2026-88798/index.md)","id":"CVE-2026-88798","markdown":"https://insights.sbomify.com/CVE-2026-88798/index.md","name":"CVE-2026-88798","record":{"aliases":["GHSA-43h4-q789-j3pr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress security plugin","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service by spoofing client IP headers to unboundedly grow a WordPress plugin option.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The Really Simple Security  WordPress plugin before 9.8.3 does not validate a client-supplied address value before using it as a storage key in one of its own options, allowing unauthenticated attackers to grow that option without bound and to slow the site's handling of missing pages.","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":"Really Simple Security (Free) \u003c 9.8.3 - Unauthenticated Unbounded Option Growth via Spoofed Client IP Header","id":"CVE-2026-88798","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MDJM Event Management and Mobile Events Manager - Unauthenticated Arbitrary Post Deletion","id":"CVE-2026-88802"},"packages":[],"prev":{"headline":"Vayu X \u003c 1.0.6 - Subscriber+ Arbitrary WordPress.org Plugin Installation and Activation","id":"CVE-2026-88797"},"products":["Really Simple Security"],"published":"2026-09-18","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Unknown"]},"summary":"Unauthenticated attackers can cause denial of service by spoofing client IP headers to unboundedly grow a WordPress plugin option.","url":"https://insights.sbomify.com/CVE-2026-88798/"}
