CVE-2026-39419: CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') in 1Panel-dev MaxKBCVE-2026-39419
0

CVE-2026-39419 is a vulnerability in MaxKB versions 2. 7. 1 and below that allows an authenticated user to bypass sandbox result validation and spoof tool execution results. The attacker exploits Python frame introspection to read a UUID from bytecode constants and writes a forged result directly to file descriptor 1, bypassing stdout redirection. By calling sys. exit(0), the attacker terminates the wrapper before legitimate output is printed, causing the service to trust the spoofed response. This issue is fixed in version 2. 8. 0.
