- CVE-2026-48558CRIT 10KEVEPSS 81%
SimpleHelp versions 5.5.15 and prior and 6.0 pre-release versions contain an authentication bypass vulnerability in the OIDC authentication flow. When OIDC authentication is configured, identity tokens submitted during login are accepted without verifying their cryptographic signature. In a vulnerable configuration, a remote, unauthenticated attacker can submit a forged token containing arbitrary identity claims to obtain a fully authenticated technician session. In some configurations, this may also allow bypass of multi-factor authentication. No user interaction is required.
- CVE-2024-57726CRIT 9.9KEVEPSS 66%
SimpleHelp remote support software v5.5.7 and before has a vulnerability that allows low-privileges technicians to create API keys with excessive permissions. These API keys can be used to escalate privileges to the server admin role.
- CVE-2024-57728HIGH 7.2KEVEPSS 64%
SimpleHelp remote support software v5.5.7 and before allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file (i.e. zip slip). This can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user.
- CVE-2024-57727HIGH 7.5KEVEPSS 97%
SimpleHelp remote support software v5.5.7 and before is vulnerable to multiple path traversal vulnerabilities that enable unauthenticated remote attackers to download arbitrary files from the SimpleHelp host via crafted HTTP requests. These files include server configuration files containing various secrets and hashed user passwords.
