Thanks for calling this out. On re-review, I agree that my original description overstated the issue. DBFILE is passed as a separate argument to pihole-FTL sqlite3; it is not interpolated into the SQL statement. The SQL itself is static, so this is not SQL injection, and the claim that an attacker could inject arbitrary SQL commands was incorrect. The security-relevant part of the change is the argument boundary:
The -- ensures that a configured database path beginning with - cannot be interpreted as a sqlite3 option. The path validation additionally restricts DBFILE to the expected filesystem-path character set. I’ll update the PR description to remove the SQL-injection/CRITICAL claim and describe this as defensive argument/path validation instead. I’ll also move the validation before the log flushing so an invalid configuration fails before making any changes. If the project doesn’t consider this hardening necessary given how |

…eLogFlush.sh DBFILE is sourced from FTL configuration (files.database) and passed as a positional argument to pihole-FTL sqlite3. The SQL statement is static; this is not SQL injection. The hardening addresses two separate concerns: - `--` prevents a database path beginning with `-` from being misinterpreted as a sqlite3 option (argument injection / option smuggling). - The allowlist regex restricts DBFILE to expected filesystem-path characters, rejecting values that fall outside the normal configuration range. The validation is now performed before any log files are flushed so that an invalid configuration fails cleanly without partial side effects. Signed-off-by: anupamme <mediratta@gmail.com>

The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.
