Description

AzuraCast before 0.23.4 contains a code injection vulnerability in the ConfigWriter::cleanUpString() method that fails to sanitize Liquidsoap string interpolation sequences, allowing authenticated users with Media or Profile permissions to inject arbitrary Liquidsoap code into station configuration. Attackers can inject #{process.run()} expressions into playlist URLs or station metadata fields that execute shell commands as the azuracast user when the station restarts.

CVE-2026-100835

Contrast Security's Contrast platform before version 1.16.0 allows remote attestation relay attacks, enabling attackers to impersonate a trusted Coordinator or workload by relaying forged TEE attestation reports. This flaw bypasses the intended binding of attestation to specific hardware, undermining the integrity of Contrast's attested TLS (aTLS). The vulnerability can be exploited by intercepting traffic between the CLI and Coordinator or between the Coordinator and an attested component.
