In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was ignored. Instead, the member should be skipped if either call returns None.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":5.7},"cvss_v3":null,"cwes":["CWE-22","CWE-59"],"references":["https://github.com/python/cpython/commit/2eb0c2f1dc71847731b6ab30aebefd058d482a7f","https://github.com/python/cpython/commit/3105a3498aaf681ce128cf5baf83c2e5574267c5","https://github.com/python/cpython/commit/764fd0af8d9e19d3684a58d2e58bf770f0605036","https://github.com/python/cpython/commit/9c17bace90f88dfba6d0e2fe23c8e7ae35f83955","https://github.com/python/cpython/commit/a4919937a4e1e69a0d178909c6f20557eca5d1d0"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-87910","score":0.00609,"percentile":0.48875,"date":"2026-10-25"},"kev":null,"osv":[],"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).
