CVE-2026-58233
HighCVSS 7.6Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
A vulnerability in the SAP Change and Transport System Attach Tool (ctsattach) allows an authenticated attacker to supply a specially crafted archive file. Processing this file by the application's library triggers insecure deserialization, leading to remote code execution (RCE) on the system.
Risk Assessment
Successful exploitation enables the attacker to execute arbitrary code, extract sensitive information, and gain control over the system and its processes. This has a high impact on data confidentiality and integrity, with a low impact on system availability.
Recommendation
Immediately apply the patch provided by SAP for the ctsattach tool. Until the patch is applied, avoid processing unknown or untrusted archive files.

Under specific conditions, an attacker can register an attacker-controlled FIDO2 credential against a target account and then authenticate as that user. This issue affects on-premises deployments only.

In Submariner's cert-auth mode, connection configuration is built from unvalidated free-form strings from the CRD. A malicious cluster can publish a CableName with newlines and ipsec.conf directives, allowing injection of arbitrary configuration or command execution via leftupdown hooks, leading to remote code execution as root on the gateway node.

In the PREVAIL eBPF verifier before version 0.2.4, the abstract transformer treats writes through a T_CTX-typed base register as a silent no-op. An attacker can craft an eBPF program that overwrites a context field, reloads it as T_PACKET, and dereferences an attacker-controlled address, and PREVAIL will report the program as safe.
- CVE-2026-53670Critical
In the PREVAIL eBPF verifier before version 0.2.4, EbpfTransformer::add() silently skips offset-variable updates when the destination register carries a non-singleton typeset. Subsequent bounds checks use the stale offset and accept out-of-bounds memory accesses, so a crafted BPF program passes verification even though it would corrupt memory at runtime.

Joro before version 1.1.1 in default proxy mode exposes a local API on 127.0.0.1:9090 with no authentication and wildcard CORS. A malicious website can reach privileged endpoints, including uploading a native plugin and triggering a restart, leading to unauthenticated remote code execution as the operator's user.

A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches allows an unauthenticated remote attacker to execute code with root privileges. TCP ports 43210 and 43211 are accessible in the default L3 VRF, and crafted input can lead to code execution or crash of the S1HAL process causing device reload.

Looking Glass prior to version 1.3.5 contains an OS Command Injection vulnerability resulting from an unanchored regular expression in the input validation layer. This issue has been patched in version 1.3.5.
- CVE-2026-82955Critical
In the current development version of Eclipse aeriOS, the KrakenD instance in the API Gateway had disable_jwk_security hard-coded to true, disabling TLS certificate verification when retrieving JWKS. This could allow an attacker to intercept communication and provide a malicious JWKS, compromising token validation. The issue has been fixed by making the parameter configurable and defaulting to false.
Original NVD description (English source)
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.
