OpenSSF/OSV advisory MAL-2026-10134 confirms this npm version as malicious. stella-cli/telegram-bot.mjs hardcodes a Telegram bot API token (BOT\_TOKEN = "8923551485:AAFw4wG8ZwOtp5rzFsnguxhu4AH-2\_ebSi0") that is controlled by the package author. When the user invokes the /tg CLI command, the package starts a Telegram bot on the installer's machine that receives messages over api.telegram.org and passes them into execSync(\`node stella-cli/index.mjs -p "${text}"\`), invoking a shell-capable AI... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-14T07:42:55.510Z - **Finished:** 2026-07-14T07:45:08.269Z - **Download time:** 504 ms - **Static scan time:** 1261 ms - **AI review time:** 130994 ms - **Total time:** 132759 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package offers an explicitly enabled Telegram remote-control bot using a hard-coded shared bot identity. After local authorization, Telegram message text reaches a shell-backed \`execSync\` call and its output is returned to Telegram. - **Trigger:** User runs \`/tg\`, authorizes a Telegram account locally, then sends a bot message. - **Impact:** An authorized or compromised Telegram account can obtain arbitrary command execution and receive resulting output. - **Evidence paths:** package.json, stella-cli/index.mjs, stella-cli/telegram-bot.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-14T07:45:08.269Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated Telegram input is shell-interpolated into a CLI invocation. - **Rationale:** Source confirms a user-invoked but unsafe remote-control capability rather than install-time malware. The hard-coded shared Telegram credential and shell interpolation warrant a warning. - **Files touched:** package.json, stella-cli/index.mjs, stella-cli/telegram-bot.mjs - **Network endpoints:** https://api.telegram.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** \`stella-cli/telegram-bot.mjs\` embeds a Telegram bot credential and polls \`api.telegram.org\`., \`stella-cli/index.mjs\` exposes bot startup only through the explicit \`/tg\` command., Authenticated Telegram text is interpolated into an \`execSync\` shell command in \`stella-cli/telegram-bot.mjs\`., Command output is sent back to the Telegram chat, enabling remote command-result disclosure., The bot persists authorization and session state under its own \`.stella\` configuration directory. - **Evidence against:** \`package.json\` has no \`preinstall\`, \`install\`, \`postinstall\`, or \`prepare\` hook., Telegram polling begins only after the user runs \`/tg\`., Remote command handling checks a locally stored authorized-user list before execution., No source evidence found of automatic environment-variable or credential-file harvesting., No foreign AI-agent configuration mutation was found. ## Affected versions and remediation This report applies to stella-coder@5.3.6. - Avoid installing stella-coder@5.3.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
