fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

Impact fast-uri canonicalizes a host to its ASCII form only when the input carries an explicit scheme. When resolve resolves a scheme-relative reference //host/ against a scheme-bearing base, it still emits the host verbatim even though the effective scheme is known, so re-parsing the resolved UR...

NPM: fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

fast-uri: fast-uri: Host confusion via skipped IDN canonicalization

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...

SUSE CVE-2026-75931

fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is returned with its host verbatim and no error set. As a result fast-uri's own entry points disagr...

PYSEC-2026-3558 datamodel-code-generator vulnerable to arbitrary local file read via JSON-Schema `$ref` (`file://` and `../` traversal), bypassing `--no-allow-remote-refs`

Summary datamodel-code-generator resolves JSON-Schema $ref targets that point at the local filesystem without restricting them to the input/base directory and without honoring the remote-reference security control. In the default configuration, an attacker who controls an input schema a "paste yo...

Mozilla: Incorrect parsing of relative URLs starting with "///"

The Mozilla Foundation Security Advisory describes this flaw as: Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal "/../" part in the path could be used to override the specified host. This could contribute to security problems in web sites...
