Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27823 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- egroupware/egroupware (Packagist): affected all versions; fixed in 23.1.20260224\n- egroupware/egroupware (Packagist): affected all versions; fixed in 23.1.20260224\n- egroupware/egroupware (Packagist): affected from 26.0.20251208; fixed in 26.2.20260224\n- egroupware/egroupware (Packagist): affected from 26.0.20251208; fixed in 26.2.20260224\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-2026-27823/ (Markdown: https://insights.sbomify.com/CVE-2026-27823/index.md)","id":"CVE-2026-27823","markdown":"https://insights.sbomify.com/CVE-2026-27823/index.md","name":"CVE-2026-27823","record":{"aliases":["GHSA-h9qx-v5xp-ph8p"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"EGroupware collaboration suite","requires_auth":"low_privilege","summary":"Authenticated attackers can achieve remote code execution via improper authorization and file primitives, potentially allowing unauthenticated access if self-registration is enabled.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"A vulnerability has been identified in EGroupware that may lead to Remote Code Execution (RCE).

The vulnerability stems from improper authorization checks combined with a file write primitive and an arbitrary file read vulnerability, which together enable full system compromise.
