Apache Software Foundation Apache Neethi vulnerabilities

CVE-2026-42404 [HIGH] CWE-918 CVE-2026-42404: Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy referenc Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP adddresses. From 3.2.2, only http or https URIs are allowed, and

CVE-2026-66143 [HIGH] CWE-400 CVE-2026-66143: It is possible to bypass the maximum number of normalized policy alternatives that was introduced in It is possible to bypass the maximum number of normalized policy alternatives that was introduced in Apache Neethi 3.2.2 via certain crafted policies, which may lead to a denial of service attack via resource consumption. Users are recommended to upgrade to version 3.2.3, which fixes this issue.

CVE-2026-42403 [HIGH] CWE-400 CVE-2026-42403: Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy d Apache Neethi does not properly detect circular references in policy definitions. When a WS-Policy document contains circular policy references (where Policy A references Policy B which references Policy A), the policy normalization process can enter an infinite loop or cause excessive recursion, leading to a stack overflow or application hang. An att

CVE-2026-91863 [HIGH] CWE-674 CVE-2026-91863: A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nestin 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.

CVE-2026-66144 [HIGH] CWE-400 CVE-2026-66144: Although remote policy references are not retrieved during policy normalization, if they are manuall Although remote policy references are not retrieved during policy normalization, if they are manually retrieved via the API it can cause a denial of service attack if a huge policy is retrieved. Users are recommended to upgrade to version 3.2.3, which fixes this issue by imposing a default maximum size on data read from remote policy references.

CVE-2026-42402 [HIGH] CWE-400 CVE-2026-42402: Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy n Apache Neethi is vulnerable to a Denial of Service attack through algorithmic complexity in policy normalization. Specially crafted WS-Policy documents can trigger an exponential Cartesian cross-product expansion during the normalization process, causing unbounded memory allocation that exhausts the JVM heap. This occurs when the normalization process

CVE-2026-91866 [HIGH] CWE-770 CVE-2026-91866: A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponen 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-2026-91864 [HIGH] CWE-770 CVE-2026-91864: A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which N 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-2026-91865 [HIGH] CWE-770 CVE-2026-91865: A small WS-Policy document using repeated policy references can force Neethi to re-expand the same r 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-2026-66142 [HIGH] CWE-400 CVE-2026-66142: Apache Neethi is vulnerable to uncontrolled recursion when parsing policies that lack policy Ids or Apache Neethi is vulnerable to uncontrolled recursion when parsing policies that lack policy Ids or with deeply nested structures, which may lead to a denial of service attack when parsing policies due to runtime memory exhaustion. Users are recommended to upgrade to version 3.2.3, which fixes this issue.

CVE-2026-91867 [MEDIUM] CWE-400 CVE-2026-91867: When Neethi fetches a remote policy reference, it only limits the time per read, not the whole trans 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.
