Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-71236 in the wild and no public exploit code.\n\nAffected product: grocy. 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-2026-71236/ (Markdown: https://insights.sbomify.com/CVE-2026-71236/index.md)","id":"CVE-2026-71236","markdown":"https://insights.sbomify.com/CVE-2026-71236/index.md","name":"CVE-2026-71236","record":{"aliases":["GHSA-c924-wcfj-cr8j"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Grocy web application","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into Grocy by exploiting a double-decoding flaw in the API request body parser, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Grocy's API request-body parser (controllers/Api/BaseApiController.php, GetParsedAndFilteredRequestBody) purifies incoming field values with HTMLPurifier, then manually reverses HTML-entity encoding of the resulting output by replacing \u0026amp;lt;, \u0026amp;gt;, and \u0026amp;amp; back to \u003c, \u003e, and \u0026 immediately after purification.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Grocy - Stored XSS via HTMLPurifier Output Double-Decode","id":"CVE-2026-71236","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Miantang IoT-PHP - Unauthenticated SQL Injection in /userlogin","id":"CVE-2026-71237"},"packages":[],"prev":{"headline":"Magistrala IoT Platform - Unrestricted Go/Lua Script Execution in Rules Engine","id":"CVE-2026-71235"},"products":["grocy"],"published":"2026-08-05","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":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["grocy"]},"summary":"Attackers can inject malicious scripts into Grocy by exploiting a double-decoding flaw in the API request body parser, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2026-71236/"}
