It more closely conforms to the relevant RFCs and adds support for URI and URL templates. Security Fix(es): Within the URI template implementation in Addressable, two classes of URI template generate regular expressions vulnerable to catastrophic backtracking: 1. Templates using the `*` (explode) modifier with any expansion operator (e.g., `{foo*}`, `{+var*}`, `{#var*}`, `{/var*}`, `{.var*}`, `{;var*}`, `{?var*}`, `{&var*}`) generate patterns with nested unbounded quantifiers that are O(2^n) when matched against a maliciously crafted URI. 2. Templates using multiple variables with the `+` or `#` operators (e.g., `{+v1,v2,v3}`) generate patterns with O(n^k) complexity due to the comma separator being within the matched character class, causing ambiguous backtracking across k variables. When matched against a maliciously crafted URI, this can result in catastrophic backtracking and uncontrolled resource consumption, leading to denial of service. The first pattern was partially addressed in 2.8.10 for certain operator combinations. Both patterns are fully remediated in 2.9.0. Users of the URI parsing capabilities in Addressable but not the URI template matching capabilities are unaffected.(CVE-2026-35611) An update for rubygem-addressable is now available for openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP2,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4,openEuler-24.03-LTS. openEuler Security has rated this update as having a security impact of high.
