Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit c1e81c510c48, unchanged since the check below.
PERMISSION_SHELL_UNDECLARED OBFUSCATION_ENCODED_BLOB
Why this grade
- PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
internal/cmd/admin/products/download_permissions_darwin.go, line 15
cmd := exec.Command("/bin/chmod", "-N", "/dev/fd/3") - OBFUSCATION_ENCODED_BLOB Medium
Contains a long base64 shaped string in a file that should be readable.
internal/output/image_test.go, line 154
err := base64.StdEncoding.DecodeString("UklGRrIBAABXRUJQVlA4TKUBAAAvSsAYAA8w//M///MfeJAkbXvaSG7m8Q3GfYSBJekwQztm/IcZlgwnmWImn2BK7aFmBtnVir6q//8VOkFE/xm4baTIu8c48ArEo6+B3zFKYln3pqCl
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
