GHSA-jgvc-94c8-3chc: pygeoapi (CVE-2026-42352)

Package	Ecosystem	Affected	Fixed in
pygeoapi	PyPI	>=0.23.0, <0.23.3	0.23.3

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

pygeoapi versions 0.23.0 up to but not including 0.23.3 are vulnerable to server-side request forgery through the subscriber object in OGC API - Processes execution requests, which can make HTTP requests to internal services. The source indicates the attack needs no authentication. Upgrade to pygeoapi 0.23.3, which disables requests to internal resources by default unless allowed through the new allow_internal_requests setting. Until then, disabling process-based resources in the pygeoapi configuration is a workaround.
