CVE-2026-55739 Crater - Missing Tenant-Ownership Check in CustomerPolicy Allows Cross-Company Customer Data Theft and Deletion

Crater isolates data per companyid, and its Invoice/Estimate/Payment/Expense policies enforce both a Bouncer ability check and -hasCompany-companyid. CustomerPolicy's view/update/delete methods omit the company-ownership check entirely, checking only the blanket ability. Route-model-bound custome...

CVE-2026-45103

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned...

sssd: sssd: GPO cache path traversal via unsanitized gPCFileSysPath allows Kerberos authentication bypass

A path traversal flaw was found in SSSD's AD GPO provider. The adgpoextractsmbcomponents function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL...

Flyto2 Core: ${env.VAR} interpolation reads any env secret despite env.get being denylisted

SummaryThe capability policy denies the env.get and env.loaddotenv modules by default, with the stated reason that they read arbitrary host environment variables API keys, DSNs and are a secret-exfil risk. But the workflow engine's variable resolver expands $env.VAR for any environment variable...
