This scale is used often in Turkish Music. But I don't know if it has a name in Western Music. Does it ?
The technical term for the scale seems to be the Minor "Gypsy" Scale and it is also known as the Flamenco Mode.
The basic idea is it is a combination of two Phrygian Dominant tetrachords, or a Phrygian Dominant with a Major 7th scale degree.
Here are the links that show both scales match the pattern above and includes the root scale of it the Phrygian Dominant scale:
Maqam Suzidil (not a very Western name, but if you try to understand Turkish music, this might get you somewhere) says this and some other sites. Looks like they (Arabic, Persian, Turkish) have an interesting way of classifying the scales by decomposing them into (usually) tetrachords which all have their own "personality". I didn't explore this much but Wikipedia gives some introduction.
That scale is known as the Double Harmonic scale (at least that's the title of its Wikipedia page here).
Double Harmonic. Hijaz Kar (Arabic). Suzidil (Turkish). Chromatic, as per Byzantine Liturgical practice. As someone else noted earlier, Rhaag Bhairav. That intervallic pattern, even if the exact intonation is different from tradition to tradition, is quite common.
Closest I found was a Spanish Phrygian 1 - ♭2 - 3 - 4 - 5 - ♭6 - ♭7 - 1
only difference is the 7th degree...maybe your scale has accidental on the 7th
