An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-26747 exists.\n\nAffected product: n/a. 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-2026-26747/ (Markdown: https://insights.sbomify.com/CVE-2026-26747/index.md)","id":"CVE-2026-26747","markdown":"https://insights.sbomify.com/CVE-2026-26747/index.md","name":"CVE-2026-26747","record":{"aliases":["GHSA-xf4f-qj26-72pf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Monica personal CRM","requires_auth":"none","summary":"Attackers can poison password reset links via Host header injection, potentially leading to account takeover in Monica CRM.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"monica","vendor":"monicahq"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax"}],"description":"A Host Header Poisoning vulnerability exists in Monica 4.1.2 due to improper handling of the HTTP Host header in app/Providers/AppServiceProvider.php, combined with the default misconfiguration where the \"app.force_url\" is not set and default is \"false\".
