CVE-2026-91867
MediumCVSS 4.3Summary
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).
Risk Assessment
A malicious or misconfigured policy server can exhaust threads in an application using Neethi, leading to denial of service. The impact depends on the number of concurrent requests and the application's configuration.
Recommendation
Upgrade Neethi to version 3.2.4 or later, which fixes this issue. Until then, consider limiting trust in remote policy sources and enforcing timeouts at the network layer.
Other vulnerabilities in Neethi
See all- CVE-2026-91866High
A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
- CVE-2026-91865High
A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
- CVE-2026-91864High
A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi copies into memory without counting it against its size limits, exhausting the heap (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
- CVE-2026-91863High
A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nesting-depth limit and exhaust the thread stack, crashing the parser (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
