| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2021-46872 | An issue was discovered in Nim before 1.6.2. The RST module of the Nim language stdlib, as used in NimForum and other products, permits the javascript: URI scheme and thus can lead to XSS in some applications. (Nim versions 1.6.2 and later are fixed; there may be backports of the fix to some earlier versions. NimForum 2.2.0 is fixed.) | [email protected] | 6.1 | 0.54% | 2023-01-13 | 2026-06-17 |
| CVE-2022-23602 | Nimforum is a lightweight alternative to Discourse written in Nim. In versions prior to 2.2.0 any forum user can create a new thread/post with an include referencing a file local to the host operating system. Nimforum will render the file if able. This can also be done silently by using NimForum's post "preview" endpoint. Even if NimForum is running as a non-critical user, the forum.json secrets can be stolen. Version 2.2.0 of NimForum includes patches for this vulnerability. Users are advised t | [email protected] | 7.7 | 1.32% | 2022-02-01 | 2026-06-17 |
| CVE-2020-23171 | A vulnerability in all versions of Nim-lang allows unauthenticated attackers to write files to arbitrary directories via a crafted zip file with dot-slash characters included in the name of the crafted file. | [email protected] | 5.5 | 0.66% | 2021-08-10 | 2026-06-16 |
| CVE-2021-29495 | Nim is a statically typed compiled systems programming language. In Nim standard library before 1.4.2, httpClient SSL/TLS certificate verification was disabled by default. Users can upgrade to version 1.4.2 to receive a patch or, as a workaround, set "verifyMode = CVerifyPeer" as documented. | [email protected] | 5.9 | 0.49% | 2021-05-07 | 2026-06-16 |
| CVE-2021-21374 | Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS without full verification of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution. | [email protected] | 8.1 | 1.03% | 2021-03-26 | 2026-06-16 |
| CVE-2021-21373 | Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS by default. In case of error it falls back to a non-TLS URL http://irclogs.nim-lang.org/packages.json. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution. | [email protected] | 7.5 | 1.16% | 2021-03-26 | 2026-06-16 |
| CVE-2021-21372 | Nimble is a package manager for the Nim programming language. In Nim release version before versions 1.2.10 and 1.4.4, Nimble doCmd is used in different places and can be leveraged to execute arbitrary commands. An attacker can craft a malicious entry in the packages.json package list to trigger code execution. | [email protected] | 8.3 | 3.64% | 2021-03-26 | 2026-06-16 |
| CVE-2020-15690 | In Nim before 1.2.6, the standard library asyncftpclient lacks a check for whether a message contains a newline character. | [email protected] | 9.8 | 3.18% | 2021-01-30 | 2026-06-16 |
| CVE-2020-15694 | In Nim 1.2.4, the standard library httpClient fails to properly validate the server response. For example, httpClient.get().contentLength() does not raise any error if a malicious server provides a negative Content-Length. | [email protected] | 7.5 | 2.33% | 2020-08-14 | 2026-06-16 |
| CVE-2020-15693 | In Nim 1.2.4, the standard library httpClient is vulnerable to a CR-LF injection in the target URL. An injection is possible if the attacker controls any part of the URL provided in a call (such as httpClient.get or httpClient.post), the User-Agent header value, or custom HTTP header names or values. | [email protected] | 6.5 | 2.05% | 2020-08-14 | 2026-06-16 |
| CVE-2020-15692 | In Nim 1.2.4, the standard library browsers mishandles the URL argument to browsers.openDefaultBrowser. This argument can be a local file path that will be opened in the default explorer. An attacker can pass one argument to the underlying open command to execute arbitrary registered system commands. | [email protected] | 9.8 | 4.21% | 2020-08-14 | 2026-06-16 |
