An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88857 in the wild and no public exploit code.\n\nAffected product: OrdaSoft.com OrdaSoft Joomla Gallery 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-2026-88857/ (Markdown: https://insights.sbomify.com/CVE-2026-88857/index.md)","id":"CVE-2026-88857","markdown":"https://insights.sbomify.com/CVE-2026-88857/index.md","name":"CVE-2026-88857","record":{"aliases":["GHSA-7jj4-5xhm-pp7r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Joomla gallery extension","requires_auth":"high_privilege","summary":"Authenticated privileged users can upload and execute arbitrary PHP files due to missing validation in the OrdaSoft Joomla Gallery extension.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Joomla","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Joomla Extension - OrdaSoft.com - Authenticated, Privileged Remote Code Execution in OrdaSoft Joomla Gallery extension for Joomla \u003c 6.2.7 - The extensions saveWatermark() copied an uploaded file into a web-accessible directory using the client-supplied filename exactly as sent, with no extension check, no content check, and no filename sanitisation of any kind.
