{"cve":"CVE-2026-106442","nvd":{"published":"2026-10-06T19:18:13.170","modified":"2026-10-07T15:17:11.900","status":"Awaiting Analysis","description":"Hydra is a framework for elegantly configuring complex applications. From 1.3.4 until 1.3.6 and 1.4.0.dev9, the instantiate() target blacklist introduced for CVE-2026-68508 incompletely checks the effective callable selected by the target field. Execution wrappers such as timeit.timeit, executable deserialization through pickle.loads, aliases, callable-returning helpers, generic dispatch, and deferred calls can obscure or defer the effective target and bypass name-based authorization. An attacker who causes an application to instantiate untrusted Hydra configuration can use these gaps to execute code with the application's privileges. This issue is fixed in versions 1.3.6 and 1.4.0.dev9.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-184"],"references":["https://github.com/hydra-ecosystem/hydra/commit/2c82bbb3f39603b336cb852461739fdf7a38798a","https://github.com/hydra-ecosystem/hydra/commit/f462811117b5ecfd2ed652ed52d6b4e3771bd943","https://github.com/hydra-ecosystem/hydra/pull/3412","https://github.com/hydra-ecosystem/hydra/pull/3413","https://github.com/hydra-ecosystem/hydra/releases/tag/v1.3.6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106442","score":0.00161,"percentile":0.05196,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rqx7-p7vv-w7hr","url":"https://osv.dev/vulnerability/GHSA-rqx7-p7vv-w7hr","summary":"Hydra instantiate target blacklist bypasses permit code execution","modified":"2026-10-15T14:55:41.619923213Z","packages":[{"ecosystem":"PyPI","name":"hydra-core","purl":"pkg:pypi/hydra-core","ranges":[">=1.3.4 <1.3.6"],"fixed":["1.3.6"]},{"ecosystem":"PyPI","name":"hydra-core","purl":"pkg:pypi/hydra-core","ranges":[">=1.4.0.dev0 <1.4.0.dev9"],"fixed":["1.4.0.dev9"]}]},{"id":"PYSEC-2026-4223","url":"https://osv.dev/vulnerability/PYSEC-2026-4223","summary":"Hydra instantiate target blacklist bypasses permit code execution","modified":"2026-10-15T14:45:06.445110031Z","packages":[{"ecosystem":"PyPI","name":"hydra-core","purl":"pkg:pypi/hydra-core","ranges":[">=1.3.4 <1.3.6",">=1.4.0.dev0 <1.4.0.dev9"],"fixed":["1.3.6","1.4.0.dev9"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
