CVE-2026-66858
HighCVSS 8.7Summary
Vulnerability in the protocol skip routine in several Apache Thrift bindings that does not apply the recursion limit, allowing deep nesting of unknown fields to exhaust the stack. Affects Python C++ accelerator, PHP, Perl, Lua, Smalltalk, and OCaml libraries. Affects versions before 0.25.0.
Risk Assessment
An attacker can cause stack exhaustion, leading to process crash and denial of service.
Recommendation
Upgrade Apache Thrift to version 0.25.0 or later.

Original NVD description (English source)
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.
