6.207 ERR_PNPM_FROZEN_LOCKFILE_WITH_OUTDATED_LOCKFILE Cannot perform a frozen installation because the version of the lockfile is incompatible with this version of pnpm
6.207
6.207 Try either:
6.207 1. Aligning the version of pnpm that generated the lockfile with the version that installs from it, or
6.207 2. Migrating the lockfile so that it is compatible with the newer version of pnpm, or
6.207 3. Using "pnpm install --no-frozen-lockfile".
6.207 Note that in CI environments, this setting is enabled by default.

failed to solve: process "/bin/sh -c pnpm install --frozen-lockfile" did not complete successfully: exit code: 1
I did a quick patch by removing --frozen-lockfile from the command in server/docker/front/Dockerfile but updating the pnpm-lock.yaml is probably the correct thing to do, I just don't know how to do it.
Authorization passwords are checked like: if auth != config['SERVER_PASSWORD']

An attacker could potential recover the password faster then guessing. A guessed password that has the first byte correct takes longer to check then a password that has the first byte wrong. Once the first byte is found, one can find the next byte and so on.

The attacker would need a lot of requests, as there can be quite some jitter and noise in the network, so it's not a very realistic attack, but might be feasable with enough samples.
