net/url: Incorrect parsing of IPv6 host literals in net/url

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid...

Content-Type Override

Parse Server is vulnerable to Content-Type Override. The vulnerability is due to missing consistency validation between the file extension and the provided Content-Type header, where the Content-Type is passed unchanged to storage adapters that serve files based on this header, allowing an attack...

Hono: Non-breaking space prefix bypass in cookie name handling in getCookie()

Summary A discrepancy between browser cookie parsing and parse handling allows cookie prefix protections to be bypassed. Cookie names that are treated as distinct by the browser may be normalized to the same key by parse, allowing attacker-controlled cookies to override legitimate ones. Details...

GHSA-4GX2-PC4F-WQ37 FastFeedParser has an infinite redirect loop DoS via meta-refresh chain

Summary When parse fetches a URL that returns an HTML page containing a tag, it recursively calls itself with the redirect URL — with no depth limit, no visited-URL deduplication, and no redirect count cap. An attacker-controlled server that returns an infinite chain of HTML meta-refresh response...
