Description détaillée

Shiori's CheckToken function (internal/domains/auth.go) validates only the JWT's HMAC signature and returns the embedded claims.Account object unmodified, never re-fetching the account from the database. No session store or token-revocation mechanism exists in the codebase. Deleting an account or demoting it from owner to a regular role has no effect on tokens already issued to that account — a deleted or demoted owner's token continues authenticating with its original owner-level privileges until natural expiry, which can be up to 30 days with 'remember me' enabled.

CVE-2026-16022

@oblique/cli 15.4.0 contains an OS command injection vulnerability in the project creation functionality. The CLI constructs shell commands through string concatenation and executes them with execSync(). A user-controlled project-name argument is inserted into the shell command without proper neutralization, allowing shell metacharacters to execute additional operating-system commands when the CLI is invoked with a crafted project name.

CVE-2026-71256

nanoMODBUS through v1.23.0 contains an out-of-bounds stack read leading to a wild-pointer write in nmbs_read_device_identification_basic() / recv_read_device_identification_res() in nanomodbus.c. A fixed 3-element stack array order[3] = {0,1,2} maps object IDs to buffer indices. The server-supplied object_id field (0-255, read directly from the wire) is used without any bounds check as buf_index = order[object_id]. When a malicious Modbus server sends a Read Device Identification response with object_id >= 3, this reads an out-of-bounds/garbage byte from the stack adjacent to order[], which is then used as an index into a 3-element buffers[] array of char* pointers. The resulting wild pointer is passed to strncpy() as the destination, causing an arbitrary-address write with server-controlled data.
