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-2026-84186 in the wild and no public exploit code.\n\nAffected product: PrestaShop. 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-2026-84186/ (Markdown: https://insights.sbomify.com/CVE-2026-84186/index.md)","id":"CVE-2026-84186","markdown":"https://insights.sbomify.com/CVE-2026-84186/index.md","name":"CVE-2026-84186","record":{"aliases":["GHSA-24v7-phg9-x7cg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"E-commerce platform","requires_auth":"none","summary":"Attackers can spoof IP addresses via X-Forwarded-For headers in reverse proxy setups, bypassing IP-based controls like maintenance mode allowlists and evading security logs.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Vulnerability involving incorrect access control in the Tools::getRemoteAddr() function in PrestaShop, which allows the client’s IP address to be spoofed via the X-Forwarded-For header when the application is running behind a reverse proxy, load balancer or CDN. The application incorrectly processes the IP address string and uses the address controlled by the visitor rather than the one provided by the trusted infrastructure, allowing an unauthenticated remote attacker to cause the application to interpret their connection as originating from an arbitrary IP address. This condition allows IP-based controls, such as the maintenance mode allowlist, to be bypassed, as well as enabling the forgery of security and audit logs and the evasion of third-party mechanisms that rely on the IP address, such as geolocation checks, fraud detection or request throttling.","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":"Incorrect access control in PrestaShop","id":"CVE-2026-84186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"AVideo on_publish.php Missing Authentication Check via RTMP Callback","id":"CVE-2026-84187"},"packages":[],"prev":{"headline":"Jwcrypto: jwcrypto: general json jws kid binding bypass during jwkset verification","id":"CVE-2026-84185"},"products":["PrestaShop"],"published":"2026-09-07","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":"2026-09-08","vendors":["PrestaShop"]},"summary":"Attackers can spoof IP addresses via X-Forwarded-For headers in reverse proxy setups, bypassing IP-based controls like maintenance mode allowlists and evading security logs.","url":"https://insights.sbomify.com/CVE-2026-84186/"}
