救驾（jiujiastudy）是留学生的 Canvas / Moodle 学习手帐：盯 deadline、排本周该学什么、按状态给建议。用户提到课程、作业、deadline、考试、Canvas、Moodle、老师，或说「现在什么情况」「最近要交什么」「这周学什么」「做完了」「没状态 / 累 / 来不及」「交之前检查」「想问老师」「做学习页」「一直在拖 / 开不了头」时使用；第一次用时自己完成设置，只向用户要学校网址（Canvas 另要 token）。
Compatibility: Not stated.
Grade C
One Medium finding. Read the report before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_HOST_FROM_INPUT
Why this grade
- NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
