CVE-2026-91123

Discourse is an open-source discussion platform. Prior to 2026.1.8, 2026.6.3, 2026.7.2, and 2026.8.0, the iframe src traversal guard did not treat literal backslashes as path separators after decoded dot segments. A crafted source could therefore pass an allowediframes subpath check while browser...

CVE-2026-91123 Discourse: Reject literal backslash path separators in iframe src traversal guard

fast-uri: fast-uri: Server-side request forgery via malformed IPv6 normalization

A flaw was found in fast-uri, a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not fully validate the IPv6 grammar, allowing invalid trailing text in an authority to be silently discarded. This can lead to a malformed, attacker-controlled host being normalized into a...

Updated perl-URI packages fix a security vulnerability

Apply Unicode NFC normalization in URI::idna nameprep so IDNA host encoding matches other clients instead of emitting a non-standard, non-round-tripping A-label CVE-2026-19953...

elysia has Inefficient Algorithmic Complexity and Interpretation Conflict

Elysia v1.4.28 is vulnerable to denial-of-service attacks due to CPU exhaustion in the form data normalization code. Elysia uses getAll to retrieve value from FormData. It is called directly relative to the total number of key-value pairs in the form data. The total amount of work the for loop ha...

fast-uri: fast-uri: Security bypass due to inconsistent host case normalization

A flaw was found in fast-uri, a dependency-free URI parser. This vulnerability occurs because the software folds the host to lowercase before percent-decoding it, allowing percent-encoded uppercase characters to bypass this normalization. A remote attacker could exploit this by crafting a malicio...

SUSE CVE-2026-73551

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's URL normalization does not recognize dot and dotdot path segments when they carry semicolon parameters. A request such as /user/..;foo=bar/admin is therefor...

UBUNTU-CVE-2026-93709

Dancer2 versions before 2.2.0 for Perl serve a layout as a page when an equivalent spelling of its path misses the guard in the AutoPage handler. The handler compares the request path against the layout directory name as text, while the lookup that follows canonicalises it. A doubled slash, a dot...
