Fyi : The version (.101) on Play Store is vulnerable to an active exploit, and the Auto-Update feature of Playstore has been halted. So any Graphene user who has installed this in the past 2-years from Play Store is running an unpatched version. Per the developer on Play Store details :
NOTE: Updates over Google Play is currently halted due to technical reasons. In the meantime, see https://github.com/termux/termux-app#installation
Latest version is v0.118.0.
NOTICE: It is highly recommended that you update to v0.118.0 or higher ASAP for various bug fixes, including a critical world-readable vulnerability reported at https://termux.github.io/general/2022/02/15/termux-apps-vulnerability-disclosures.html. Also reminding again to users who have installed termux apps from google playstore that playstore builds are deprecated and no longer supported. It is recommended that you shift to F-Droid or GitHub releases
Or did the additional hardening of Graphene mitigate these exploits?
