protobufjs: Denial of Service via unbounded recursive JSON descriptor expansion

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

cve-program · CVE-2026-45740

Published

protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.8 and 8.2.0, protobufjs could recurse without a depth limit while expanding nested JSON descriptors through Root.fromJSON() and Namespace.addJSON(). A crafted JSON descriptor with deeply nested namespace definitions could cause the JavaScript call stack to be exhausted during descriptor loading. This vulnerability is fixed in 7.5.8 and 8.2.0.

## Summary protobufjs could recurse without a depth limit while expanding nested JSON descriptors through `Root.fromJSON()` and `Namespace.addJSON()`. A crafted JSON descriptor with deeply nested namespace definitions could cause the JavaScript call stack to be exhausted during descriptor loading. ## Impact An attacker who can provide JSON descriptors loaded by an application may be able to crash the process or otherwise cause schema loading to fail with a stack overflow. This affects applications that load JSON descriptors from untrusted sources with affected versions. ## Preconditions - The application must load JSON descriptor data influenced by an attacker. - The crafted descriptor must contain deeply nested `nested` namespace objects. - The affected `Root.fromJSON()` / `Namespace.addJSON()` descriptor expansion path must process the crafted input. ## Workarounds Avoid loading untrusted protobuf JSON descriptors with affected versions. If immediate upgrade is not possible, reject excessively nested descriptor structures at an outer validation boundary where feasible, or isolate descriptor loading in a process that can be safely restarted.
