kana-dojo: Improper Neutralization of Special Elements used in an OS Command
CVE-2026-48547 is a high-severity improper neutralization of special elements used in an OS command vulnerability in kana-dojo from Lingdojo, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 0.1.18 as the first without the flaw, so updating kana-dojo to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.91% chance of exploitation within 30 days, higher than 61% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update kana-dojo to 0.1.18 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
KanaDojo contains a command injection vulnerability that allows an attacker with pull request access to execute arbitrary shell commands by inserting shell metacharacters into the version or changes fields of patchNotesData.json, which are interpolated unsanitized into a child_process.execSync() call in the release.yml workflow. Attackers can have a malicious pull request merged to trigger the GitHub Actions runner with contents write permissions and access to GITHUB_TOKEN.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
