CVE-2026-49837

A flaw was found in GoBGP, an open-source Border Gateway Protocol BGP implementation. A remote attacker could send a specially crafted BGP OPEN message, causing the BGP OPEN capability parser to misinterpret data. This issue arises because the parser may read capability values beyond their declar...

The vulnerability of the DecodeFromBytes() function in the pkg/packet/bgp/bgp.go file of the BGP OPEN Message Handler component of the GoBGP protocol allows a attacker to increase their privileges.

The vulnerability of the DecodeFromBytes function in the pkg/packet/bgp/bgp.go file of the BGP OPEN Message Handler component is related to access control deficiencies. Exploiting this vulnerability could allow a malicious actor to enhance their privileges remotely...

The vulnerability of the decoder handlers in the BGP OPEN messages parser of the GoBGP edge gateway module pkg/packet/bbg protocol allows a attacker to cause a service failure.

The vulnerability of the decoder handlers for BGP OPEN messages in the GoBGP border gateway module’s pkg/packet/bbg protocol relates to unvalidated array indexing. Exploiting this vulnerability could allow a malicious actor to cause service failures...

The vulnerability of the BGP OPEN message parser in the pkg/packet/bbg module of the edge gateway protocol GoBGP allows a attacker to compromise the integrity of the protected information.

The vulnerability of the BGP OPEN message parser in the pkg/packet/bbg module of the edge gateway protocol GoBGP is related to the execution of operations beyond the buffer boundaries. Exploiting this vulnerability could allow a malicious actor to compromise the integrity of the protected...
