Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-1812 exists.\n\nAffected product: bolo-blog bolo-solo. 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-2026-1812/ (Markdown: https://insights.sbomify.com/CVE-2026-1812/index.md)","id":"CVE-2026-1812","markdown":"https://insights.sbomify.com/CVE-2026-1812/index.md","name":"CVE-2026-1812","record":{"aliases":["GHSA-7jwc-4rcq-547h"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"bolo-solo blog","requires_auth":"low_privilege","summary":"Remote attackers can exploit a path traversal vulnerability in the importFromCnblogs function to read or modify arbitrary files on the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"bolo-solo","vendor":"adlered"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability has been found in bolo-blog bolo-solo up to 2.6.4.
