SB2026092021 - openEuler 24.03 LTS SP3 update for python-starlette

Description

This security bulletin contains information about 1 vulnerability.

1) Unsafe reflection (CVE-ID: CVE-2026-48817)

CWE-ID: CWE-470 - Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to invoke unintended endpoint methods.

The vulnerability exists due to use of externally-controlled input to select code in HTTPEndpoint request dispatch when processing a request with a non-standard HTTP method. A remote attacker can send a specially crafted request to invoke unintended endpoint methods.

Exploitation requires an HTTPEndpoint subclass to be registered through Route(...) without an explicit methods= argument, and the subclass must expose additional methods whose names match a non-standard HTTP method token shape, accept a single request argument, and return a response.

Remediation

Install update from vendor's website.
