The attachment 172653 [details] contains a chart (embedded OLE object) and despite the document is read-only it is possible to start the chart module per double-click and modify the object. I wonder if this is a security/safety risk.
On Windows builds, the docoment opens read-only. Double click of the chart OLE opens its dialog--changes attempted are not applied including the OLE object dialog. Document can't be saved. Are you able to save the "edited" document, while in read-only mode? If not either, then no I don't see an issue. Read-only is doing what it should. =-testing-= Version: 7.1.3.2 (x64) / LibreOffice Community Build ID: 47f78053abe362b9384784d31a6e56f8511eb1c1 CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded Version: 7.2.0.0.alpha1+ (x64) / LibreOffice Community Build ID: 3b57ebb445df8a2bc3d916ea79f8af45e20e4e62 CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded
@Heiko, see comment 1. Tested with Version: 7.4.0.0.alpha0+ / LibreOffice Community Build ID: d47628f287f4377394c4ff488c433bfe254b6abe CPU threads: 4; OS: Linux 5.11; UI render: default; VCL: gtk3 Locale: cs-CZ (cs_CZ.UTF-8); UI: en-US Calc: threaded and I was not able change the chart in read only mode.
True, changes are not applied. So it's just a minor usability flaw.
