An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-90900 in the wild and no public exploit code.\n\nAffected product: joomshaper.com Easy Store extension for Joomla. 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-2026-90900/ (Markdown: https://insights.sbomify.com/CVE-2026-90900/index.md)","id":"CVE-2026-90900","markdown":"https://insights.sbomify.com/CVE-2026-90900/index.md","name":"CVE-2026-90900","record":{"aliases":["GHSA-rf4v-mqxp-593r"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla extension","requires_auth":"none","summary":"Attackers can trick logged-in users into submitting unauthorized product reviews or spam in the Easy Store Joomla extension due to missing CSRF token verification.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Joomla Extension - joomshaper.com - Missing CSRF Token Verification in Storefront Product Review Submission in Easy Store extension 1.0.0-3.0.0 - The product review submission endpoint (index.php?option=com_easystore\u0026task=product.addReview) accepted submissions without verifying an anti-CSRF token (the check had been commented out in code).
