Apache Struts: Unbounded request body read in the REST plugin

Allocation of resources without limits or throttling vulnerability in the Apache Struts REST plugin. A request body is read into memory without any bound on how much will be accepted, so a single request can cause the server to allocate memory in proportion to its size, exhausting the Java heap and denying service to other users. No additional setting has to be enabled. Applications that do not use the REST plugin are not affected. This issue affects Apache Struts: from 2.1.8 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.

CVE-2026-104712 High · 7.5 CWE-405 Oct 5, 2026

Apache Struts: Disproportionate response size when rendering BigDecimal request parameters

Asymmetric resource consumption (amplification) vulnerability in Apache Struts. When a request parameter is bound to an arbitrary-precision decimal (java.math.BigDecimal) property that is then rendered through the Struts tag library, the framework can produce a response many orders of magnitude larger than the request, allowing an unauthenticated remote attacker to exhaust server CPU and outbound network capacity with sustained low-volume traffic. Applications that do not bind request parameters to BigDecimal properties, or never render such a property through the Struts tag library, are not affected. This issue affects Apache Struts: from 2.5.14 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.

CVE-2026-104711 Critical · 9.8 CWE-917 Oct 5, 2026

Apache Struts: OGNL injection in the legacy RESTful action mapper

Improper neutralization of special elements used in an expression language statement ('Expression Language Injection') vulnerability in Apache Struts. If the application is configured to use the legacy RESTful action mapper, a crafted request can inject an OGNL expression that may lead to remote code execution. Struts 7 is affected only when the OGNL allowlist is disabled; it is enabled by default. Applications using the default action mapper, the restful2 mapper, or the Struts REST plugin are not affected. This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.

CVE-2026-59265 High · 8.8 CWE-426 Oct 2, 2026

Apache OpenOffice, Apache OpenOffice: Opening a malicious document can lead to system takeover

A code execution issue in the Java integration in Apache OpenOffice v4.1.16 and earlier allows a crafted untrusted document to trigger executing arbitrary (even remote) code when opened by the user. This issue is expected to be fixed in version 4.1.17, which is in the release candidate phase. Until then, users can mitigate this issue by disabling Java runtime integration in the Preferences dialog. This prevents the attack. If this is not possible, or as an extra precaution, you can avoid opening open untrusted files entirely. Once 4.1.17 is released, upgrade to that version to fix the issue.

CVE-2026-102795 Critical · 9.3 CWE-284 Oct 2, 2026

Apache Traffic Server: SNI to Host header matching policy is not properly enforced

Improper Access Control vulnerability in Apache Traffic Server. This issue affects Apache Traffic Server: from 9.0.0 through 9.2.14, from 10.0.0 through 10.1.3. Users are recommended to upgrade to version 9.2.15 or 10.1.4, which fixes the issue. This CVE supersedes CVE-2026-41920, whose record listed the affected 9.x versions as 9.0.0 through 9.1.14 and the fixed version as 9.1.15. All 9.2.x releases before 9.2.15 are affected.

Loop with unreachable exit condition ('infinite loop') vulnerability in Apache Thrift c_glib bindings. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-83745 High · 8.7 CWE-130 Oct 2, 2026

Apache Thrift, Apache Thrift: WebSocket frame decoders allocate the payload buffer from the declared length, not the bytes received (Node.js, D)

Memory allocation with excessive size value, Improper handling of length parameter inconsistency vulnerability in Apache Thrift nodejs and D lang bindings. Both bindings' WebSocket server transports read the payload length out of the frame header and allocate that many bytes immediately, without checking that the bytes have arrived. A single ~14-byte frame therefore commits as much memory as it cares to declare -- measured at 513 MiB against the Node.js server and 2 GiB against the D transport -- and in the Node.js case the connection is left open afterwards, so the frame can simply be sent again. This issue affects Apache Thrift before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-83663 High · 8.7 CWE-674 Oct 2, 2026

Apache Thrift: TFramedTransport and THeaderTransport re-enter Read once per frame that carries no payload (Go)

Uncontrolled Recursion vulnerability in Apache Thrift go bindings. Both Go transports satisfy a read out of a buffered frame and, when that frame yields no payload bytes, read the next frame and call `Read` again instead of looping. A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-83632 Critical · 9.2 CWE-122 Oct 2, 2026

Apache Thrift: C++ THttpTransport grows its line buffer without bound

Allocation of resources without limits or throttling, Integer overflow or wraparound, Heap-based buffer overflow vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.

CVE-2026-66858 High · 8.7 CWE-674 Oct 2, 2026

Apache Thrift, Apache Thrift, Apache Thrift, Apache Thrift, Apache Thrift, Apache Thrift: skip() does not apply the recursion limit (Python accelerator, PHP, Perl, Lua, Smalltalk, OCaml)

The protocol skip routine in several Apache Thrift bindings did not apply the binding's recursion limit, so a message that nests unknown fields deeply enough can exhaust the stack. Affected: the Python C++ accelerator (the pure-Python protocols are not affected), the PHP library and its thrift_protocol extension, and the Perl, Lua, Smalltalk and OCaml libraries. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.
