CVE-2026-91867: Vulnerability in Apache Software Foundation Apache Neethi
When Neethi fetches a remote policy reference, it only limits the time per read, not the whole transfer, so a server that trickles bytes slowly can keep the fetch alive indefinitely and tie up the calling thread (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
AI Analysis
Technical Summary
CVE-2026-91867 describes a denial of service vulnerability in Apache Neethi. The flaw occurs during the fetching of remote policy references, where the time limit is applied only per read rather than the entire transfer. This allows a malicious or slow server to trickle bytes slowly, keeping the fetch operation alive indefinitely and causing the calling thread to be tied up, leading to resource exhaustion. The Apache Software Foundation has fixed this issue in version 3.2.4.
Potential Impact
An attacker controlling a remote policy server can cause a denial of service by keeping the fetch operation alive indefinitely, tying up server resources and potentially degrading service availability for legitimate users.
Mitigation Recommendations
Users should upgrade Apache Neethi to version 3.2.4 or later, where this issue is fixed. No other mitigation is indicated by the vendor advisory.
