CVE-2022-30973 | Missing fix for CVE-2022-30126 in 1.28.2

We failed to apply the fix for CVE-2022-30126 to the 1.x branch in the 1.28.2 release. In Apache Tika, a regular expression in the StandardsText class, used by the StandardsExtractingContentHandler could lead to a denial of service caused by backtracking on a specially crafted file. This only affects users who are running the StandardsExtractingContentHandler, which is a non-standard handler. This is fixed in 1.28.3.

5.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
