An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-6666 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pgbouncer (Bitnami): affected all versions; fixed in 1.25.2\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-2026-6666/ (Markdown: https://insights.sbomify.com/CVE-2026-6666/index.md)","id":"CVE-2026-6666","markdown":"https://insights.sbomify.com/CVE-2026-6666/index.md","name":"CVE-2026-6666","record":{"aliases":["AZL-86243","BIT-pgbouncer-2026-6666","CLEANSTART-2026-XI13738","DEBIAN-CVE-2026-6666","GHSA-4463-8rvf-rj9f","MINI-2j8r-xv56-5cv2","UBUNTU-CVE-2026-6666"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PgBouncer connection pooler","requires_auth":"none","summary":"A null pointer dereference in PgBouncer allows a malicious server to cause a crash by sending an error response without an SQLSTATE field.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"PostgreSQL","cpe":[{"product":"pgbouncer","vendor":"pgbouncer"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A possible null pointer reference in PgBouncer before 1.25.2 could lead to a crash, if a server sends an error response without SQLSTATE field.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-08-03","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-03T01:27:13Z","kind":"github_poc","ref":"https://github.com/George0Papasotiriou/CVE-2026-6666-XPC-Service-NSKeyedUnarchiver-Deserialization-Attack-macOS-iOS-simulation-","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"PgBouncer crash in kill_pool_logins_server_error","id":"CVE-2026-6666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"PgBouncer missing authorization check in KILL_CLIENT admin command","id":"CVE-2026-6667"},"packages":[{"ecosystem":"Bitnami","fixed":["1.25.2"],"introduced":["0"],"last_affected":[],"package":"pgbouncer","purl":"pkg:bitnami/pgbouncer","source":"BIT-pgbouncer-2026-6666"}],"prev":{"headline":"PgBouncer buffer overflow in SCRAM","id":"CVE-2026-6665"},"products":["PgBouncer"],"published":"2026-05-09","related":[{"cvss_score":8.1,"headline":"PgBouncer buffer overflow in SCRAM","id":"CVE-2026-6665","kev_date_added":null,"published":"2026-05-09"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2015-6817","kev_date_added":null,"published":"2017-05-23"},{"cvss_score":7.5,"headline":"PgBouncer integer overflow in PgBouncer network packet parsing","id":"CVE-2026-6664","kev_date_added":null,"published":"2026-05-09"},{"cvss_score":7.5,"headline":"Untrusted search path in auth_query connection in PgBouncer","id":"CVE-2025-12819","kev_date_added":null,"published":"2025-12-03"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2015-4054","kev_date_added":null,"published":"2017-05-23"},{"cvss_score":4.3,"headline":"PgBouncer missing authorization check in KILL_CLIENT admin command","id":"CVE-2026-6667","kev_date_added":null,"published":"2026-05-09"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["n/a"]},"summary":"A null pointer dereference in PgBouncer allows a malicious server to cause a crash by sending an error response without an SQLSTATE field.","url":"https://insights.sbomify.com/CVE-2026-6666/"}
