PYSEC-2026-3465 FiftyOne App server uses wildcard CORS (Access-Control-Allow-Origin: *), enabling cross-origin reads of local server data

Impact The FiftyOne App/API server fiftyone/server/app.py and the /media route fiftyone/server/routes/media.py unconditionally set a permissive CORS header Access-Control-Allow-Origin: on their responses. Because the embedded App server runs locally and is unauthenticated, this allows any website...

PYSEC-2026-3539 sanic-cors contains an improper regular expression in the try_match() function

sanic-cors version 2.2.0 and prior contains an improper regular expression in the trymatch function in saniccors/core.py that uses re.match without end-anchoring. This allows an attacker to bypass CORS origin allowlists by registering a domain that begins with a trusted origin string, to gain...

PYSEC-2026-3472 jupyter-server is vulnerable to CORS origin validation bypass when the `allow_origin_pat` configuration is used

A vulnerability in jupyter-server versions 1.12.0 through 2.17.0 allows an attacker to bypass CORS origin validation when the alloworiginpat configuration is used. The issue arises from the use of re.match for validating the Origin header, which only anchors at the start of the string. This allow...

Netty: Security Control Bypass via CORS Short-Circuit Failure

Summary Netty's CorsHandler provides a shortCircuit configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can b...
