CVE-2026-58233
SAP Change and Transport System Attach Tool (ctsattach) allows an authenticated attacker to supply a specially crafted archive file which, when processed by the application�s library, can trigger insecure deserialization and lead to remote code execution (RCE) on the system. Successful exploitation requires a victim to process the malicious archive, enabling the attacker to execute the RCE and extract sensitive information and gain control over the system and its processes. This vulnerability has a high impact on confidentiality and integrity of the data, with a low impact on the availability of the system.
