      <title>CVE-2026-59990 — Jawn: Uncontrolled nesting depth in JSON parser</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-59990</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; typelevel jawn&lt;/p&gt;
&lt;p&gt;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 java.lang.OutOfMemoryError is a fatal Scala error that is not ordinarily handled by scala.util.Try or cats.effect.IO, causing denial of service. This issue is fixed in version 1.7.0.&lt;/p&gt;</description>
