Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a HashCollisionNode collision bucket that is scanned linearly, allowing an attacker who controls keys inserted into a Map, such as through Immutable.Map(obj), Immutable.fromJS(obj), state.merge(userObject), or mergeDeep, to craft many colliding keys and degrade insertion and lookup to consume disproportionate CPU. This issue is fixed in versions 4.3.9 and 5.1.8.

According to its self-reported version number, the Atlassian Jira application running on the remote host is prior to 10.3.25 or 10.4.x prior to 11.3.11. It is, therefore, affected by multiple vulnerabilities, including flaws in bundled third-party dependencies :

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, Immutable.Map
    and Immutable.Set keep keys that share the same 32-bit hash in a HashCollisionNode collision bucket that
    is scanned linearly, allowing an attacker who controls keys inserted into a Map, such as through
    Immutable.Map(obj), Immutable.fromJS(obj), state.merge(userObject), or mergeDeep, to craft many colliding
    keys and degrade insertion and lookup to consume disproportionate CPU. This issue is fixed in versions
    4.3.9 and 5.1.8. (CVE-2026-59880)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, Immutable.Map     and Immutable.Set keep keys that share the same 32-bit hash in a HashCollisionNode collision bucket that     is scanned linearly, allowing an attacker who controls keys inserted into a Map, such as through     Immutable.Map(obj), Immutable.fromJS(obj), state.merge(userObject), or mergeDeep, to craft many colliding     keys and degrade insertion and lookup to consume disproportionate CPU. This issue is fixed in versions     4.3.9 and 5.1.8. (CVE-2026-59880)

Note that Nessus relies on the presence of the package as reported by the vendor.
