🔒 Fix command injection in xargs with bash -c

[Ven0m0]

🎯 What: Fixed a potential command injection vulnerability in Cachyos/Scripts/Android/media-optimizer.sh.
⚠️ Risk: Files with malicious names (e.g., containing $(command)) could execute arbitrary code when processed by the script's parallel image optimization logic.
🛡️ Solution: Switched from xargs -I{} interpolation to xargs -n 1 and passed the filename as a positional parameter ($1) to the bash -c subshell.

Code Review

This pull request modifies the parallel image processing logic in media-optimizer.sh by switching xargs from -I{} to -n 1 and passing the image path as an argument to the subshell. However, a critical issue was identified where sourcing the script via source "$0" inside the subshell triggers the execution of the main function, causing the subshell to exit with an error. A suggestion was provided to correctly pass the script path and arguments to the subshell to avoid this behavior.

❌ Subshell execution fails ∴ source "$0" triggers main function execution in subshell.

🔍 Analysis

• bash -c '...' "$0" sets subshell $0 to outer script path.
• source "$0" inside subshell makes BASH_SOURCE[0] equal to $0.
• [[ "${BASH_SOURCE[0]}" == "${0}" ]] evaluates to true » main "$@" executes.
• Subshell $@ contains the image file path ($1).
• main parses image file as target_dir » [[ ! -d $target_dir ]] is true » prints error & exits subshell with code 1.
• process_image is never executed.

🛡️ Fix

• Pass "bash" as $0 to subshell, and $0 (script path) as $1.
• Sourced script sees $0 as "bash" ∴ [[ "${BASH_SOURCE[0]}" == "${0}" ]] is false » main skipped.
• Pass image file as $2.

Suggested change

	printf '%s\0' "${image_files[@]}" | xargs -0 -P "$MEDIA_OPT_THREADS" -n 1 bash -c '
	source "$0"
	process_image "{}"
	process_image "$1"
	' "$0"
	printf '%s\0' "${image_files[@]}" | xargs -0 -P "$MEDIA_OPT_THREADS" -n 1 bash -c '
	source "$1"
	process_image "$2"
	' "bash" "$0"

Cachyos/Scripts/Android/media-optimizer.sh	502	Subshell execution fails because source inside xargs triggers main function execution instead of sourcing the script library

The existing comment from @gemini-code-assist correctly identifies that the fix introduces a logic bug: the xargs -n 1 bash -c pattern causes the subshell to source the script and immediately trigger main because of the BASH_SOURCE check at line 674. The suggested fix (bash -c source "$1" process_image "$2" "bash" "$0") is correct.
