CVE-2026-124540——
——0JSON::XS versions before 4.05 for Perl allow stack exhaustion via nested tagged values under allow_tags in decode_tag.
With allow_tags, "(" starts a tagged value. Its tag and value are decoded recursively, and each can start another tagged value. Unlike arrays and objects, this nesting is not counted against max_depth.
A run of "(" bytes exhausts the C stack and triggers an uncatchable segmentation fault regardless of max_depth.21hCVE-2026-1280827.5 ALT—
——0AutoMapper is a convention-based object-object mapper in .NET. Prior to 15.1.4 and from 16.0.0 until 16.3.0, AutoMapper increments type depth only after creating the destination, so recursive mapping performed through constructor parameters occurs before MaxDepth is counted. Destinations built through positional records or other constructors, and recursive ConstructUsing mappings that call context.Mapper, can therefore bypass explicit MaxDepth values and the default limit of 64. Deep attacker-influenced input can throw an uncatchable StackOverflowException and terminate the process. This issue is fixed in versions 15.1.4 and 16.3.0.1dCVE-2026-1280817.5 ALT—
——0AutoMapper is a convention-based object-object mapper in .NET. Prior to 15.1.4 and from 16.0.0 until 16.3.0, AutoMapper can recurse without an effective MaxDepth limit when mapping polymorphic graphs through Include or IncludeBase, runtime-typed object or interface members, nested Dictionary<string, object> or ExpandoObject sources, or recursive ConvertUsing type converters. Deep attacker-influenced graphs on these paths can throw an uncatchable StackOverflowException and terminate the process. This issue is fixed in versions 15.1.4 and 16.3.0.2dCVE-2026-493417.5 ALT—
——0BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to version 1.5.1, there is a remotely reachable denial-of-service vulnerability in bacnet-stack affecting the default demo server built from the unmodified apps/server/main.c. This issue has been patched in version 1.5.1.1dCVE-2026-1282385.3 MED45.5%
——14Scapy before 2.8.0 contains an uncontrolled recursion vulnerability in the BER/ASN.1 decoder in scapy/asn1/ber.py that allows unauthenticated remote attackers to crash parsing applications. Attackers can send a single 833-byte packet with 250 nested ASN.1 SEQUENCE structures to trigger an unhandled RecursionError, terminating TLS, SNMP, X.509, or LDAP parsers even with safe=True.1dCVE-2026-1280205.9 MED39.3%
——12FrankenPHP before 1.13.2 contains an uncontrolled recursion vulnerability in its PHP-to-Go array converter that fails to detect circular references in PHP arrays. Passing a self-referential array to frankenphp_log() or returning one from a worker callback triggers a fatal Go stack overflow, terminating the entire server process.2d
