Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100387 in the wild and no public exploit code.\n\nAffected product: pgpointcloud pointcloud. 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-2026-100387/ (Markdown: https://insights.sbomify.com/CVE-2026-100387/index.md)","id":"CVE-2026-100387","markdown":"https://insights.sbomify.com/CVE-2026-100387/index.md","name":"CVE-2026-100387","record":{"aliases":["GHSA-cfw8-qrr2-2ccr"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PostgreSQL extension","requires_auth":"low_privilege","summary":"Authenticated users can read heap memory or crash the database via crafted WKB data in the pgPointcloud extension.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"pgPointcloud through 1.2.5 contains a heap out-of-bounds read vulnerability in dimensional patch WKB deserialization that allows authenticated database users to read adjacent heap memory.
