Dasel vulnerabilities

Dasel versions 3.0.0 through 3.11.2 have a bug in the tokenizer that reads out of bounds when a selector ends with whitespace, causing a panic and process termination. Input passed through Tokenize() or dasel.Query is also affected.

Dasel versions 3.0.0 through 3.11.1 lack a depth limit when parsing nested JSON or XML. Deeply nested attacker-controlled input can exhaust the Go goroutine stack and cause an unrecoverable fatal error that terminates the entire process.

A vulnerability in Dasel versions 3.0.0 through 3.10.1 causes an infinite loop when tokenizing an unterminated regex literal (e.g., r/). An attacker can exploit a crafted selector string to exhaust CPU resources.

Dasel versions 3.0.0 through 3.10.0 have a vulnerability in the parseCurRune function of the tokenizer that fails to perform bounds checking when processing escape sequences in quoted strings. An attacker can supply a crafted selector string, causing an index-out-of-range panic.
