GHSA-CC4V-RVGP-2PF3 Jawn: Uncontrolled nesting depth in JSON parser

The Jawn parser before 1.6.1 is vulnerable to a denial of service attack via untrusted input. Impact A remote attacker who can submit JSON to any jawn-backed parse method can exhaust JVM heap and trigger java.lang.OutOfMemoryError. This is treated by Scala as a fatal error and not typically handl...

CVE-2026-82409

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, indexer/common.go serializedDataForUpdateAccounts places the attacker-controlled acc.Name value into an Elasticsearch bulk JSON and NDJSON request without escaping it. The SetAccountName transaction accepts val...

CVE-2026-82409

Prior to version 1.7.20 , the Klever-Go blockchain implementation is vulnerable to Elasticsearch bulk / painless injection due to improper escaping of the acc.Name value in indexer/common.go. Because the SetAccountName transaction accepts raw UTF-8 characters including quotes, backslashes, and ne...

DEBIAN-CVE-2026-61814

Jawn is an open source JSON parser. Prior to 1.7.0, Jawn's AsyncParser can perform quadratic work when a single JSON token is delivered across many small chunks because each absorb call rescans the incomplete token from the start. A remote attacker who controls untrusted JSON input and its chunk...

CVE-2026-59990

Jawn is an open source JSON parser. Prior to 1.7.0, Jawn parse methods accept arbitrarily deep JSON array and object nesting without a depth limit, allowing a remote attacker who can submit untrusted JSON to grow parser contexts until the JVM heap is exhausted. The resulting...
